Apologies if I'm missing something obvious but is it possible to run BigBox in a window, rather than fullscreen? I know LaunchBox is intended for windowed use but I really prefer the advanced animations of BigBox and want to use this to pick games while streaming, without covering up information elsewhere on my screen. I've got a 1440p monitor and like to run games in a 1080p window for streaming purposes, using the edges for stream information windows and chat and such. Thanks!
