I would like for there to be an indication on the Action! HUD that shows if whether or not the microphone is activated and recording. I'd discovered with a video I had only just now uploaded that the entire last eight minutes where I had actually been commentating was completely silent because I had accidentally hit the microphone PTT key.
Being able to turn off my microphone during the middle of video recording so that the focus could be on the gameplay is one of the most crucial features with Action! that keeps me with the program, but it'll get really frustrating, really fast, when I have to periodically turn it off and then forget to count how many times I press the button.
