 Use x11 shm instead of XGetImage (https://stackoverflow.com/questions/43442675/how-to-use-xshmgetimage-and-xshmputimage).
 
 Add a hotkey to record/stream/replay/screenshot region.
+
+Do xi grab for keys as well. Otherwise the ui cant be used for keyboard input if a program has grabbed the keyboard, and there could possibly be a game that grabs the keyboard as well.
+
+Make inactive buttons gray (in dropdown boxes and in the front page with save, etc when replay is not running).
