I've been using Phoenix for 2 years straight and it's been pretty smooth sailings. Kasper has done an excellent job maintaining and implementing new features every once in a while, thanks Kasper!

My personal configuration is written in TypeScript and I maintain typings for Phoenix as well. I try to find ways to improve my every-day and implement them in Phoenix, things like: moving/resizing windows, coffee timer, monitor brightness, terminal hotkey, etc. In the past I've used it to track what applications I spend my time in or to automatically switch Karabiner-Element profiles based on which monitor is connected. If you're looking for inspiration, feel free to have a look:
