The last update removed the UI scaling setting. So on 4k my UI is really small and hard to read. I hope the devs don’t focus on the mainstream that uses max 1080p or 800x600 monitors and leave the higher resolutions out of support.
At least you can access all of the UI though. On 1280 x 720 I can’t hit the manufacture button on Secret Project ships and Destroyers because it’s off the screen 
Will be fixed
