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.
