I think it would be very beneficial to:
a. have drag and drop function available, to move the shot around on top of existing Move to .. function.
b. allow color coding not just the lower corner of shot (which is not visible if collapsed/minimized), but the entire top section of the shot window (just like Preview orange and Program green). And add few more categories to your 6 + all that is available now.
c. Force clear last frame of vMix caller. (right click Force Clear Last Frame)
Thank you.
