[Enhancement] Local "Last played" track data in queue

[Morgon]

Curious if this would be useful to anyone else... but after having 500+ songs in my queue, sometimes I kind of lose track of what's been played, or what might be lost in the jumble of constantly reorganizing the queue...

In any case, I'm proposing some way of saving/displaying when I've last played a track (if not anyone in the room, assuming you were there when it played). This could live on the queue itself, maybe as a flyout or tooltip.

I'd imagine the best way to implement this would probably be via localStorage, which makes it per-machine.. but I would imagine it would have some use.

Thoughts?
