Yes, not a top priority, but if you have some spare device to add to "stock" (but not to put into production), a quick discovery, and a button to "move" it to a kind of "offline" database is a very nice thing!
Anyway, sometimes may happen that a "production" device will become substituted by a new one. A quick way to "archive" it, without loosing a lot of precious information seems useful.
Only an opinion. If you have only a dozen of switch, is not an heavy load to do it "by hand"...
