The info panel gains a line under the lens: "Adobe Standard · in the
file", the .dcp it came from, "· off" when the photographer switched it
off, or "No camera profile · matrix only" — the ordinary case for a
CR2, worded as a fact rather than a failure. A DNG whose embedded
profile may be copied, for a body with no installed profile, also gets
"Use this profile for every Canon EOS 6D →", which saves it into the
profiles directory; the body's CR2s render through it from their next
decode.
The profiles directory is <data>/profiles, read at start-up on desktop
and Android before anything decodes. The library open path never set
the lens line; it now sets both. Labels: Camera Profile, Use Profile,
Look Amount.
Presets were a "Presets…" button in develop's top bar that opened a
sheet over the photograph, so applying one was two clicks with the
picture covered. They are now an entry pinned to the bottom of the tool
rail, apart from the tools because a preset arms nothing, and it opens a
menu beside the rail: the same sectioned rows the sheet lists, one click
to apply to the open photograph. The menu's last row, "Save or manage…",
opens the sheet, which keeps saving, renaming, reverting and importing,
since those take a name or a path.
The menu is a PopupWindow for the film list's reasons, with the list in
a clipped box of its own; the Flickable alone let its last row draw over
the manage row. Choosing from it zeroes preset-apply-count before
applying, since the grid may have left its selection count there.
The manual says where presets are now and gains a picture of the open
menu. The scenes reach the sheet through the menu and aim the manage
row from the rail's entry, as the film list's rows are aimed, because
the automation reports a popup's elements in the popup's coordinates.
Adding a labelled Help button to develop's top bar made the strip about
100 pixels wider than a 1600-pixel window. The strip scrolls, so nothing
became unreachable, but Settings was off the right-hand end until the
bar was dragged.
Help is now a square IconButton with a drawn question mark (a new "help"
icon, drawn rather than typed for the reason icons.slint gives about
Android's fonts), and screen readers still hear it as "Help". That saves
60 pixels, which was not enough alone: the strip had fit with 3 to spare
before. The rest comes from the spacing. Controls that belong together
now sit in groups at gap-sm with gap between groups: Pick and Reject,
Undo and Redo, Copy, Paste and Presets, and "?" and Settings. The empty
export-status caption no longer takes a slot and two spacings while it
has nothing to say. At 1600 wide with the panel open the whole bar now
shows, Settings included.
The grid's header keeps its worded Help button; it has room for it.
The develop "Open this list" gesture now names the "?" button, and the
gesture book is regenerated from it.
The "Controls and shortcuts" sheet was drawn by LibraryGrid, so only the
grid's Help button and its F1 could open it. Develop, where most of the
keys it lists are bound (Ctrl+E, Ctrl+Shift+C, A/D, Z, R, H, [ ]), had no
way to it: a photographer who wanted to look a shortcut up had to leave
the photograph they wanted it for.
The sheet now hangs off the shell beside the export and copy sheets, on a
`help-open` property both views set. The grid's Help button and F1 raise
it through a callback, and its keys stand down through the `sheet-open`
they already honour for the export sheet, so Escape falls through to the
shell, which closes it. Develop gains a Help button beside Settings in
its top bar, as in the library header, and F1 in its key scope; its keys
decline while the sheet is up, as they do for the other two sheets, so
nothing behind it is rated or stepped. The book already begins with the
Develop section, so from develop it opens where the reader wants it.
Tests hold the shape: the sheet is drawn by the shell and not the grid,
and develop's opening guard names all three sheets and its F1 opens this
one. The new GESTURE: block puts the develop route in the book.
An audit of every action by view against the keys the handlers bind left
develop without zoom, pan, fit or a way back to the grid, the grid without
select-none, thumbnail size or keywording, People with no key at all, and
the export and copy sheets without Enter. It also found the reverse gap
FR-UI-5 forbids: pick and reject had no route but P, X and U, and the
2026-09-19 amendment's judging in develop had not been built.
Develop: Ctrl+= and Ctrl+Plus zoom in and Ctrl+- out about the middle of the
view, Ctrl+0 fits and Ctrl+1 goes to 1:1, Shift and an arrow pan a magnified
view, G goes back to the grid, Ctrl+Y redoes, and Enter keeps a crop that hid
a mask. 0-5, P, X and U rate and flag the open photograph without moving on,
with stars and Pick/Reject in the top bar as the pointer and touch route.
= and - nudge the control last moved by a hundredth of its travel; the
framing sliders, perspective included, now count as "last moved", so R puts
them back as well. J turns the selected mask part's join chip.
Grid: Ctrl+D and Ctrl+Shift+A clear the selection, = and - resize the
thumbnails, Ctrl+K opens keywording, and Flag in the selection bar gives
pick and reject a pointer and touch route. Sidebar: Enter commits a
collection's name, and Enter or Escape hands the keyboard back to the grid,
where it used to go nowhere until something was clicked. People: Up and Down
walk the rail, F2 puts the name field under the keys, and Escape or Back now
leave the screen the way its back button does instead of doing nothing.
Sheets: Enter does what the export or copy sheet's button does.
The choices follow Lightroom where it has one. No new key steals typing: the
grid's and People's keys live on focus holders that are not ancestors of any
text field, and the sheets' Enter comes after a focused field has had it.
Every binding is tagged beside its handler, and the gate added in the
previous commit holds the two to each other.
Colour labels could be read from a Lightroom sidecar and queried by the
selector, but nothing drew one or set one, so the only labels a library
held were ones another program had written.
Every mark carries its label's initial on its colour — R, Y, G, B, P —
so a label is read without telling red from green, which is what
NFR-A11Y-3 asks of colour labels by name. A grid cell shows the mark
before its filename. In the grid, 6, 7, 8 and 9 set red, yellow, green and
blue as Lightroom's keys do, on the photograph under the pointer or on
the selection by the rule the star keys follow; the same key again takes
the label off, and over a mixed selection it sets it on all. The
selection bar gains Label, which opens the six choices — each a mark and
a name — and purple, which has no key, is there. In develop the top bar
says "Label: Green" beside the mark, opens the same choices, and 6-9
label the open photograph.
Each gesture is one catalog transaction, then the grid, the counts and
both sidecars are written as a rating's are. The filter bar gains a chip
per label, its mark and its name with a count, one at a time; the filter
is one SQL term, travels in the place record, and "All" clears it.
They sat in the develop column under a "SETTINGS" heading, which read as
application settings, and went away with the panel toggle and in the
mask and spot modes. The strip is where undo already is for the same
reason: these act on the whole edit, not on any one panel.
The paste button still names what it would apply. The TransferPanel
component is gone; the Transfer global and its Rust wiring are
unchanged.
Every panel in the develop column declared its inputs and its callbacks and
had `app.slint` bind each one to a property or a callback on the window root.
That is fine while a panel is drawn once. N9 draws them a second time, in the
portrait dock, and the wiring is what would have to be copied: `MaskPanel`
alone ran to forty lines of forwarding, and a callback added to one copy and
not the other compiles, renders, and simply does nothing on the layout nobody
was looking at.
So the wiring moved to Slint globals. A panel reads the global and calls the
global; Rust hooks the global instead of the window; and the instantiation in
the column is now the panel's name and a pair of braces — every one of the ten
children of the column, with no property that differs by placement left to
supply.
There is a global per panel family rather than one for all of them, and the
reason is an import cycle. Each panel's model struct — `ParamRow`, `MaskRow`,
`HistogramView` — is declared in the panel's own file, so a single global
holding `[MaskRow]` and `[ParamRow]` would have to live in a file importing
`masks.slint` and `adjust.slint` while both imported the global back, which
Slint rejects. Breaking that needs six model declarations relocated, which is a
change to the data model and not to the plumbing this is about. A global beside
the panel it serves also lets each name drop the prefix it was carrying only
because the window root is one flat namespace: `root.spot-radius` is
`Repair.radius`, and `root.peaking-on` is `Peaking.showing`.
`session.slint` is new and holds the two facts every family needs and none of
them owns: whether there is an open photograph to edit, and which mode the view
is in, with the three readings of the mode derived once instead of at each of
the dozen places that tested one. `ViewMode` moves there from `adjust.slint`,
where it was only ever a lodger.
Nothing on screen changes. What is not here: the tool rail and the status strip
still take their properties at the instantiation, because they are drawn once
and N9 does not copy them; the preset sheet's own state stays on the window,
because the library grid opens the same sheet and a global cannot bind the
window's state — which is why `Transfer.open-presets` is handled in
`presets.rs`, beside the summary it already had to compute.
`dr-lens` has held a complete Lensfun lookup — distortion, TCA and vignetting
coefficients from a lens name, a focal length and an aperture — with no
dependents anywhere in the workspace. The three corrections it feeds now
exist in the graph, so this connects the two and finishes the chain.
The coefficient structs stay duplicated. `dr-pipeline` is organised around
having no dependencies so its codegen is testable without a device or a
database (ARCH §6.5a), and `dr-lens` carries an XML parser and 5.5 MB of
profile data. Neither crate can convert to the other, so the conversion goes
above both, in `develop.rs`, which is the only place that sees them together.
Both traits grow the same defaulted door. The optical corrections do not sit
on the same side of the fetch — distortion and CA rewrite coordinates and are
`Warp`s, vignetting applies a gain to the pixel already there and is an
ordinary node — and fanning a profile out by which trait each happens to
implement would make the caller reason about that distinction. Each correction
takes its own share of the whole profile instead, and `set_lens_profile` walks
both lists identically.
The lookup happens in `set_source_metadata` rather than in its caller, because
that is the one place a session is told which file it came from. Doing it
there makes it unforgettable, in the shape `FilmRebake` already uses for the
other derived thing — and, more to the point, makes *clearing* unforgettable:
a session that opened a second photograph while still holding the first one's
profile would correct it for the wrong optics, invisibly, in a way that looks
exactly like the lens.
It needs the whole shot and not just a name. Distortion is interpolated across
a zoom's focal range and vignetting depends strongly on aperture — a fast
prime can be two stops down in the corners wide open and clean by f/8 — so a
lookup missing either returns coefficients measured for a shot nobody took.
Missing any of the three refuses rather than guesses.
A profile is derived, not persisted: it comes from the file's EXIF and a
database, so it is not a parameter, not in the sidecar and not undoable. What
is an edit is the manual trim beside it, which each correction composes with
the measurement — so a photographer can lean on it, override it, or work
without one.
`InfoPanel` gains a lens line, and it distinguishes three cases rather than
two. `dr-lens` states the rule it exists for: an automatic correction that
silently did nothing is worse than one the user can see is unavailable. A
session with no header draws nothing, a header naming no lens reads "Lens not
recorded", and a lens the database has never heard of reads "· no profile".
Collapsing the last two would send somebody hunting for a profile that was
never missing — which, for third-party and adapted glass, is the ordinary case.

Crop, Local and Repair were chips at the head of the develop column, sharing a
row with the adjustment groups and told apart from them by the shape of their
highlight. Three things followed from that, and only the last is cosmetic: the
column closes, so the way out of a mode went away with the way in — hence the
duplicate "Done Cropping" over the canvas; the chips are generated from the
operation set, so the widest thing in the sidebar was a row nobody had chosen
the contents of; and a mode and a filter are different kinds of state wearing
one control.
They are a fixed 60px rail down the left now, generated from a single table in
toolrail.slint. A tool is one row of it plus a drawing plus a ViewMode variant;
nothing in app.slint is touched to add one. What is left of the strip is the
group filters, so it is GroupStrip.
The column stops measuring itself. Every panel published a content-width and
declared it as min-width, and the column took the largest — which spent the
photograph's pixels on whatever happened to be widest, and moved the image
sideways when switching tools swapped one set of panels for another. It is
panel-width now, one number in style.yaml.
That number is 360 and it is measured, not picked: the contents report a
minimum of 344 in every mode, and they do not compress below it because a Text
that does not elide reports the same minimum as preferred. 320 was tried and
sliced Paste down the middle. The Flickable's viewport is floored at the
layout's minimum rather than its preferred width for the same reason — content
that is never told how much room it has cannot adapt to having less.
Removing the eight content-width declarations repairs three comments an
earlier edit had spliced sentences into. The raw histogram's note on keeping
its hint short is rewritten rather than dropped: an over-long hint no longer
widens the column, it pushes the column's minimum past the width it has and
clips the panel, which makes that constraint sharper rather than obsolete.

StatusBar and InfoPanel sat above AppWindow in app.slint, which read as
though they were part of the application shell. They are not: neither is
instantiated anywhere but the develop view, and the shell's actual job --
choosing which of the five screens is up -- is easier to follow without
two unrelated components standing in front of it.
Moved verbatim to develop.slint, matching src/develop.rs. No behaviour
change; app.slint loses 232 lines and gains one import.
