Ha, I used pyinstall and QT for the first time during a one off project. Smoothest GUI development I've ever done coming from knowing nothing about the stack. Esp. pyinstall. Had to do literally nothing for win/mac/unix builds.

To be fair though, it was a relatively simple app, but I feel that's the typical use case if you're already proficient in python and just want to add some buttons.

I don't hear about using this stack much, so I'm glad it's getting improvements + more attention!
