I know this has been suggested so many times, but I might as well bring this up again to show how important this needs to be a feature.
Here are my 2 biggest suggestions:
1. An actual recording indicator, especially in game recording mode, or make FPS overlay the recording indicator with more options. FPS overlay is only situational with not a lot of options, so it may or may not be in your videos. How about have an option to "show FPS overlay" just like "show mouse cursor"? So if people want FPS overlay in their videos, check "show FPS overlay", if not uncheck, "show FPS overlay", but it seems like the name has already been taken under "FPS" for a different purpose. There is not a lot of options for this FPS overlay and it would be cool to have more options for this.
2. In game recording mode, an option to auto record whenever a program/game starts, or auto record when a specific program/game starts. This would be handy if some people wanted to record the first few seconds of the game.
