1. Aspect ratio: Well, i think this was already being worked for so you know why.
2. Some way to lock the screen. Be it click lock behind you or something so you don't accidentally do it. And to unlock it you have to say, look down as you do now and then press two buttons with touch or look behind you/at several locations. Currently either my touch comes too close to one of the windows and activates it -> no commands go to what ever im doing. Usually ends me in the sun.. also the best place for the screen (that i prefer) is in front of me in my lap -> watching it pops up the main menu. Sun.
3. Disable browser hotkeys for youtube/etc. Just do it. Even with the focus not in the V, it seems it gets the hotkeys. Youtube video jumps around when you switch pips from systems. Or every time i do "small jump" (bound to pgdwn) my twich video mutes itself. Or then make a settings tab in the GUI.
4. Reset screen option. You know, when it just launches itself 20m outside the window and you'll have to go knock the neighbour to get your screen back..
