There are some problem need to be fixed

I pretty much like this player. But there are something need to be improve
1. I drag the music from folder into collection of vox, after that if I change the name of the folder or I move the folder to another place, vox cannot trace for that, therefore I need to drag it again. That is very unconvenience, fix that will be very helpful.
2. If the name of the song or collection is too long, vox does not show it even I put the mouse pointer on it.
3. I cannot change the cover picture of the collection by dragging the picture on it.
