I am seeking feedback on a UI addition / feature proposal before I start implementing it.

Problem

At present, all OCIO ColorSpaces are listed in a single PROP_ENUM list, which can get quite long with complicated OCIO configs.

An example OCIO config with many colorspace entries:

Proposed Solution

OCIO supports organization of ColorSpaces into “families”, and applications are encouraged to use these families when structuring menus. As an example of the desired direction this UI could take, Here is the UI for the same OCIO config in the compositing software Natron.

Open Source compositing software Natron:

I am hoping to introduce a similar nested tree UI element for presenting these colorspace lists inside Blender.

Not sure if a “tree” style UI already exists, or if extension to the DNA/RNA types might be required.
There is also additional work happening in the OpenColorIO UX working group that may be useful to incorporate.

Any feedback would be greatly appreciated.

This would be a very welcome improvement.

For enums we have a mechanism to organize the values with headings, see RNA_ENUM_ITEM_HEADING. This will still display the enum as one big menu with columns. I think beyond a certain size it should switch to submenus.

uiItemsEnumR is the code that generates the content of that type of menu now. Instead it could create a submenu for each heading.

I think this would be very welcome by studios using ACES. The name list can get incredibly long (even more so than your initial image) so this would really solve that problem
