I would like to suggest having an option for you to choose which audio you want to record during the game. In some cases you might want to capture music or a discord call with friends in the clips. In some cases you may just want the audio from the game exclusively for your clips (while you may have other audio going on at the same time).
I understand this would require Outplayed to separate different programs into different audio channels. But it is easier if Outplayed had this feature rather than having to rely on third party software.
