Comment 1 for bug 872006

i just commented under the bug #674067, but let me paste it here as well.

i second this.
i need it very much.
when i play with pioneer hw it helps me by showing key near the track in green colour by signaling that this key is compatible with the key of what is played now so it is one of the choices for the next track.

when you play for hours, and are not able to prepare everything in advance, or if you have to improvise because you read the audience, this is very helpful.

and absence of it is literally a showstopper for using mixxx in many cases.
