Quick and Precise Angle Measurement in Blender? I'm looking for a precise way to measure angles in blender.  The ruler/protractor tool is very limited with the snap to vertex frequently failing in edit mode and only showing two digits beyond the decimal point when it does work.

Are there any addons that will let me do something like select two points and measure their angle relative to the 3D cursor?
(preferably with the ability to attain more than two significant figures beyond the decimal point - somewhere beyond 6-8 would be ideal, but even just a smoother workflow than that damned ruler/protractor tool built into Blender would be amazing to have)
When in edit mode  press N and then select Mesh display> angle.
Then take a vertex and move it.
