Nice! I do something similar with my laptop using Hammerspoon: when it detects my external keyboard is connected over USB it does some setup for my desk/mobile environment (repositions dock, quits some apps, launches some apps, etc). I manage my windows in quarters and thirds using keyboard, so they don't really move about.
