How much of your library has scene-actor truth data. Ignored items are excluded from the "to do" total, so blacklisting a genre or series won't drag your progress down.
Shape the work-discovery API (/Plugins/JRay/Tasks/Pending).
Ignore hides matching items from extraction workers;
Prioritise pushes them to the front of the queue. A more
specific rule wins (item > series > genre). Setting a
rule for a target that already has one replaces it, so nothing can be both
prioritised and ignored.
