Interesting, what resolution are you running? I can add in more resolution support - as it stands it's just laptop 1366 x 768 and 1920 x 1080, which I think is a 16:9 aspect.
As for autosave, good point. I actually have it as a feature it's just not enabled because I'm constantly doing stuff to debug, but I'll roll out autosave for you in the next patch.
Thanks for the feedback!
