Personnal hammerspoon config, includes app launching, moving and resizing windows.
I've changed the location of my hammerspoon config to ~/.config/hammerspoon. This path is used inside my configs, so some things might break if you don't take that into account.
To change the location of the hammerspoon config:
defaults write org.hammerspoon.Hammerspoon MJConfigFile "~/.config/hammerspoon/init.lua"
