I was wondering if you can make it by default, or add an option to make it so Xion does not take window focus when you double click a song to begin playback. This actually happens if you try to play the song in any fashion be it right click, double click, or Enter key. It also happens if Xion is not even visible. It's not a huge inconvenience but having to click or alt tab back to the folder to play the next song can be a little tedious. I suppose I could use a mouse but that doesn't allow me to use my hand for other things, like doing my taxes. Of course, I don't need to do that right now anyways, but if I did I would be screwed.
I just checked the latest beta and this still happens.
