* We have a setting called "Display units". As a user
I'd expect this
to only influence display (as the name suggests) but nothing else
(i.e. I should be able to switch this at will without causing any
change for my document)
It doesn't →
* However, as soon as the user changes "display units"
the "Scale"
will change too! As a user I'm now frightened: Did I just change the
size of my document? Should I revert to "Scale" = 1? (if they choose
to do so it's very bad as then they'll mess up their drawing)
→ The scale does not actually change, it only appears to have changed
because it used to show uu per <other unit>
