v0.2

I have something passable for "settings". You might think that "a drop down box with four orientations" would make sense, but It would take me years to figure that out. You get two boolean toggles. The two orientation settings will always be orthogonal. One toggle switches one side between uppey-downey, the other toggle switches between lefty-righty. Changes will not be apparent until the next time you hit the rotate toggle.

You are responsible for turning off Gnome-shell's built in Autorotate.

If your device is "tablet-y" and "could possibly dock with a keyboard", Gnome-shell will probably force an orientation change on suspend/resume. There is definitely nothing that I can do about that.
