It would be great if we could set a default map rotation for all maps/projects.
For example, the roads in my municipality are oriented 15.5 degrees clockwise. So the first thing everyone in my organization does when creating a map is rotate the map -15.5 degrees so that the roads fit better on maps and are easier to work with. It would be handy if we didn't need to do that for each map.
It would also mean new users who are unaware that maps can be rotated would have properly rotated maps by default.
