DisplayShift: Plug in a monitor and choose which windows move over

Hi Product Hunt! I'm Aqib, I made DisplayShift. I dock my MacBook to a monitor every day, and every time I plugged in, my windows stayed piled on the laptop screen. Full screen apps were worse: leave full screen, drag, go full screen again. Then the Mac would sleep and macOS would shuffle everything back. So now, when a display connects, a panel drops out of the notch with every window listed. Tick what should move and it goes across, full screen apps included, behind a calm curtain instead of macOS's flashing. Unplug and everything comes home. It remembers a layout for each set of screens, puts windows back after sleep, and keeps your monitor arrangement if macOS swaps it. It's $2.99 once after a 7-day trial, no subscription, no account. I'd love to hear how you dock, and what would make this part of your day.
