Searchbar for layers or simple filters
The same idea what we can find in PS. Possibility to show just a specific layers depends type of the filter. For example showing just a lock layers will be nice or show layers with specific fill color. If I've got a huge amount of layers in the project, event if I try to naming them I spend too much time for looking for locked layer or some specific one.

Oh man, I feel so stupid right now xD Yes, there is a filter and search bar with all the options what I need. I can't explain why I didn't saw this even when I'm looking hard. Thanks again!

Pawel, Ai got the Search panel with filtering options in build 2023 (27.7)
Are you seeing these? What build are you using?
There isn’t an option to filter by a layer’s color though...
