I understand why you put everything in one single request… buuuut as per the wishlist guidelines:
As the Cut/Copy/Paste System can’t just be written once for all these usecases, i think you would need to create atleast two wishes here.
- One for File Management based Cut/Copy/Paste functionality
- One for Sample Editing Cut/Copy/Paste functionality
Unless there is another place that these two “categorisations” wouldn’t cover.
Btw, i’m not trying to be difficult 
, just trying to enforce the rules bestowed upon us
