Subject: [PATCH] home: wm: use explicit 'enable' options

This is so that I can explicitly enable them if I were to use Wayland
and Sway, given that they should be compatible with both environment.

This also means that putting them in `/home/x/` would a misnomer... Will
revisit this if and when I try out Wayland and sway...
