Freeze Groups

Would be handy to be able to freeze groups, when doing so a greyed out/non-editable region would appear on the group track (also handy for seeing what the waveform of a group of summed tracks looks like).

This would ofcoarse make it so no further tracks could be output bus’d or sent to it (would be be greyed out in output/sends list).


This would also have to “lock” the audio tracks/faders that were bus’d to that group at the time (but keep their ‘sends’ freed)
