Idea for UI enhacement:

Admin can set a color for each bookmark root in ENOVIA’s Bookmark Editor. All child bookmarks inherit that color. 
Each deeper level shows a lighter shade, so hierarchy depth is easy to see, even in complex structure.

Why it helps: faster scanning, fewer misclicks, less mental load, same view for everyone.
