Describe the problem/motivation

I have a wide monitor. As in 5120x1440p, 32:9. When I have any single window open, I really don't want to have it cover my full screen. Is there any way to set an initial maximum window size?

Describe the solution you'd like

A simple setting in the config.yaml file to have an initial maximum width and height for new windows, which can then be resized manually as needed. These initial maximum dimensions should only be applied when there are no other windows open, or as long as there is empty space left on the screen. Widths and heights could be set by pixel dimensions or percentages.

Alternatives considered

I could use per-app rules in AltSnap to enforce the max-width on a per-app basis, I suppose, but I don't actually know how it would work with GlazeWM and AltSnap essentially fighting over my window sizes.
