Hi, A quick idea iv had is to be able to lock groups. You could remove the master section and just allow each group to be locked so that they play all the time. Then you could have as many groups as you want as masters. Or if that's too CPU intensive then you could just allow any group to be the master. You would free up screen real estate and give more flexibility. Also a CPU load meter would be useful so we know when we are close to capacity.
