Hi, I've just submitted a pull request which might be a solution to this feature request.
"Add bearing entry as alternative angle entry (FS2037) #39 "

My solution allows you to enter bearings which are relative to 0 degrees at north, and are clockwise. To enter a bearing, use the format 32b26'42" which adheres to the other data entry methods.

It does not address any other areas where angles are displayed on the UI. For example, it does not solve display of angles in bearing mode. I'm still looking at this, hoping to provide a menu option under preferences for angle format as "Bearing" which will make this mode a default. I would gladly accept any guidance on the code architecture to implement these additional features.

Cheers.
