Justification
If I change my mind and want to change which layers are in which group, I have to select the ones I have to move (that can be quite a long stack with a lot of FX and masks, etc.) and drag and drop. Moreover, if I want to delete a group folder, it deletes everything inside it too. Instead, I would like a option that automatically disassembles a group into its constituent groups and layers so that it can be deleted without all the manual work of moving things around. This disassembly should maintain any lower hierarchy too.
