This was a small HUD update suggestion that crossed my mind.
I do some video game commentary and I record using both the Video recorder (MP4 Quick Sync) and Audio recorder (set to record just my mic) so I can edit my voice separate from the game. I will hit both shortcut keys at the same time so they will automatically be in sync. As of the current HUD I can tell the video is recording when the HUD turns red, however to my knowledge there is no real way to tell if the audio is recording my mic unless I alt+tab to check Action. And of course if I alt+tab the video will stop recording my game. So basically I have to trust that it is recording both. You can imagine my fear that I will record an hour long game session and quit only to find that my mic was never recording (which hasn't happened yet thankfully).
I was thinking this might be a nice addition to the HUD where it shows the different recording icons and they will individually turn red when recording/activated. Here is a small mock-up I did, the lower showing that I would be using the video recorder and audio recorder at the same time. Hope you take it into consideration. Thanks!
