My menu Window days: Float All, and all windows are floated. Docking and undocking toiols are in the View menu. But always undocked images don't seem to be an option...

You are absolutely correct. I guess I expected something like 800px, but 800w or 800h makes much more sense and it works great.

Unfortunately an additional width definition in px is not possible. Only factors... I need this a lot of times. Think of a website slider which needs a 1600px width image, a 1000px width, a 600px width and 450px width for a srcset.
