I use the mini player all day to listen to music.
Because I use apples AirPlay technology, it is not possible to control the volume over the media keys on my keyboard (this only changes the volume of the inside speakers).
It would be great if the mini player would get a volume control, so I don't have to open iTunes every time, to change it.
I have done a quick concept how I could imagine implementing it.
Cause mini player only uses the enter key to navigate, it would be simple to use the left and right arrow keys to control the volume.
Either just when you have selected the volume field, or everywhere.
What do you guys think about this idea?
