This inverts collection selection in line art.
Difference with collection line art usage flag:
- Collection line art usage is global, used to specify e.g. if a collection should appear in calculation at all.
- Invert collection selection is used to easily select a collection and "everything else other than that collection", making it convenient to set up such cases.
(User still needs to manually configure intersection filtering)
The UI is aligned correctly now without the gap in the next gif:
