[Update: Color labels for folders were added in LR 7.4 --John Ellis]
I find it difficult to navigate folders and collections in the LH panel. To some extent this is because I (unwisely) chose to use similar naming conventions.If it were possible to allow users to "Colour code" folders and collections it would make navigation much easier and also give me another way of "cataloging" photos.My suggestion would be a small colour indicator, rather like the online/offline indicator but round instead of oblong.
