The demo seems atm deadset to want to go full-screen at native resolution while the game's interface seems locked on 1080p. So on my 1440P screen i'm always looking at a 1080p game surrounded by nothing but black and alt-enter just leaves me with a massive window with blackness and a smaller game.

Being able to resize the game to either a larger or lower resolution along with a proper windowed mode would be great. Both for letting it everything be more visible on higher-resolution monitors AND for the ability of quickly switching inbetween the game and documentation since the game leans a great deal on external resources for people to get anywhere.
