Hello.
Is there a way to hide the playlist when you select a file to play? It is really anoying to click again on the tiny button after you have already selected the music you wanted.
Not atm. The rationale is that users who configure the microplayer to have it show the playlist do so because the want the playlist to show all the time (I think it would be surprising to most users if double-clicking another track would close the microplayer Playing list).
