Angular Running Dimensions

In SW2014, we are introducing Angular Running Dimension (angle dimensions that work similar to Ordinate Dimensions) which allows you to quickly dimension circular patterns from a 0deg baseline.  The options available for Angular Running Dimensions should allow you to implement ASME, ISO and other standards.  What do you think about Angular Running Dimensions, including how easy/hard they are to use?  Where might you use them?  Have you encountered any limitations while using them so far in Beta?
