- Add Xft Xresources to make fonts not ugly
- Add dunstrc now that I'm using dunst
- Manage GTK settings now that I'm free of mate-settings
- Add an i3 keybind for pcmanfm
- Make kitty font size chords +/- by 1pt and not 2pt
- Explicitly specify fonts everywhere
- Put barrier and dunst in xinitrc
- Make QT theme explicit via env var
- Move ZSH keybinds to global since Arch doesn't bind them
