Add settings

[sojusnik]

From a UX point of view, having settings where you can choose AUTO, ARROW and CRITICAL would be very nice to have.

After installing this extension, the dconf entry wasn't created automatically, so having settings, with a default entry, would solve that as well. Else people could assume, that this extension isn't working.

Happened on Ubuntu 22.04 with Gnome 42.1.

Sorry for the late response. I skipped adding a GUI for the settings, since this was for my bachelor thesis and time was sparse. However, I will add this function as soon as I find the time. Also, maybe check out #6 !
