MonitorLayout

Free. Runs in your browser.

You dock the laptop and every window jumps to the wrong screen. You undock and they all pile onto one. This takes a snapshot of where your windows are while they are right, and puts them back whenever you want.

Save as many layouts as you like: one for docked, one for the laptop on its own.
Only moves windows. It never changes your resolution or display setup, and never asks for administrator rights.
Remembers which monitor each window was on, so a layout still lands correctly when screens change size or scaling.
One small launcher file does the work on your machine. Your layouts stay on your own PC and are never uploaded.

Why I ask: I might reach out with a question about how to improve this tool, or to mention other cool tools I build. I will never give your email address to anyone else. You only have to do this once per browser.
