TODO grouping does not work as expected:
- when changing a large group of faders, the volume change is very very slow, also the feedback from server, it seems the protocol is overloaded totally
- vertical space between check boxes should be smaller
- get rid of bIsSelected
TODO minimum height of faders (dependent on style)
