Ah you dont use it in maximize screen mode? I think I can push an update for that problem. Thanks for the feedback Fox Lee!
Oh, I guess I could just maximise it! I didn't think of that XD Although, it would mean that window has a lot of empty "gutter" space in that window in my stream layout, since my avatar is mostly vertical. (And I assume that would be the case for most Tubers). So remembering window size would still me more convenient, if it's not too much trouble :)
