I spend most of my time working in OS X and I use Hammerspoon. It is really an awesome tool. It allowed me to establish truly keyboard-centric workflow. Not just for managing windows, a lot more. I also have Linux machine at home, I don't use it a lot yet I've been thinking about developing better way to work in Linux - something that lets me keep my hands in "the home row". Can someone recommend a tool similar to Hammerspoon?
