Comment 4 for bug 1403715

At the moment, the only real use would be to rate a track, since that's not in the context menu.

Aside from that, the two options are practically pretty similar, but I think this is probably a bit cleaner, because a context menu in the decks might get confusing (right-click in that area generally does something, like resetting a control). Also, this option would be better for those mostly using controllers - for example, you could map "show in library" to a controller button, and then it will make it easier to controller-browse other tracks by that artist (or by bpm what ever you have the library sorted by).
