This would be an extremely useful feature for those of us who record gameplay with 3rd party software such as FRAPS or Bandicam;
If we could trigger Mumble to start recording/stop recording with a keybind this would make available synchronized mumble recordings to overlay over gameplay footage. I'm sure this would also have uses for people who are too busy to alt+tab to Mumble to initiate a recording.
PS: Thanks for the great software. Mumble is the best.
