Feature Requst: Move units selection to preferences as a global setting
This requests dates back to the very beginning of v2.0, and possibly earlier (I cannot find the v1 code online). See this comment in the current master:
I have a PR that accomplishes this by moving the units choice into prefsdialog.ui. It also enhances the units selection by adding Points, Picas, Didot, and Cicero as available units.
