Hello
i'm probably not the first one who wants this but it looks like an easy thing to implement to me (i'm not a programmer) and it would help a lot.
Folders in Layers:
for example organising your file in lights, riggimg, stage, or if you import an mvr of a festival, organize it in 2 folders, extern /intern or local /production.
This would make my life a lot easier
Best
Christoph
