I'm not native in English so I will try my best to be clear
Is it possible to choose a resolution for any windows of any software ?
I saw there is some kind of settings with percentage in DF, but I need resolution in numbers.
For instance on a 4K or WQHD screen, force a window resolution of 1280x1024 or 1920x1080.
Or try 4:3 or 16:10 resolution on a 16:9 screen to test design rendering in Firefox/Chrome...
With a window's resolution smaller than Windows resolution of course.
