I can give you some first impressions. like the gui and also that you can see when Qspot is loading/buffer sign/serching. I really like that you can change tracks with the keyboard. Looks and works pretty good already.

issues:
*press more than one time on the arrows(change track) will result in that the client closing.
*dubble press on a track will result in that the client closing.
*scrolling with keyboard and than fast pressing enter to start a song, oftan stops qspot to stop playing any track. you have to restart qspot before you will be able to play a any track(also get segment fault a few times when doing this)

my feature list
* sorting would be nice
* missing row of most played(sort on most played from an artist).
