This looks great. Would there be an easy way to generalize this program to tiling window managers? Maybe initially I can use this by modifying the WM to forward all its keybindings to a dummy Emacs instance. For WMs is the entropy theory also applicable?

Some people use Emacs /as a tiling window manager/ :) https://github.com/emacs-exwm/exwm

it should be -- as long as you have like the right logging set up, I think the theory would also be applicable.

currently the calculations in this library are done with a clojure jar, so if you're interested, you might have an easier time calling that directly
