I was using Global Trash (see Aminet) which I found useful: simple and well done. But this is an old program and something didn't work as it should (selecting time for delete files inside trashcan didn't work).
Let' say that trashcan is not a "must have" but I bet it would be used a lot and it would be useful to have it for various reason. So, if this bounty starts, I'll be one of donors.
@Amigadave:
Sorry to read your experiencing more troubles. I really believed you solved your back problem.... Come on, man!
