so I have a youtube channle and its hard to record without it being blurry so I suggest a test mode for the people who made the game where there game always gos fullscreen juat for the ones who made the game your playing

???

I have no idea what that suppose to mean

bassically the maker of the game gets to play there games in fullscreen mode

Yeah @grazer should add an account detector to be able to detect accounts which would only work on the website though. Kind of like the platform detection behavior
