Should remove from the old collection and add to the new collection
Agreed to leave intentionally unscheduled in #musicbrianz-devel and through the scheduling game.
It might be nice to write a copy function as well as a move function. I could see using this for, say, copying a release from a collection of all my music to a smaller collection of, say, just chiptune (or so).
It would also be nice for both of these to be potentially-batch operations – i.e. from the collection page or interface popup or whatever, select N releases and a destination, then hit the move button or the copy button. Once again, this is useful for making subset collections like the one I describe above.
Reopening since this was changed anonymously.
This was in code review at http://codereview.musicbrainz.org/r/2191/ but needs more work, so I am reopening the ticket.
