* pgup/down navigation for workspaces, I may not use them, but I was
playing around
* add a lot of comments
* read the fine manual of i3lock, enable cursor that I often use to
check the device is alive, turn both backgrounds black and enable
showing of failed login attempts
* disable notify-send:ing volume changes when media keys are used as
pasystray does that by itself
* unfloat Firefox for now, even if I will likely need to float it again
when I attempt to use it on Zaldaryn.
