I didn't see this topic when searched, but I really like the way layers can be organized / grouped as in Photoshop (Layer Sets). How the sets can be collapsed (or all un-collapsed) organizing the layers dialog box. When un-collapsed, the layers can still be sorted by name or extension. Obviously, the order of the list in PS affects the display output, which is not the case in AC. I haven't decided if this would be a good or bad idea, or if it would even work, but I do like it in PS. Maybe it could be useful in AC.
