[REQ] Angular Dimension

[daiku]

I've been using Didier's Angular Dimension tool, and while I love the concept and appreciate the effort, I humbly suggest that it could benefit from some improvements. Specifically. I'd like to be able to restrict it to a specific plane, like the native protractor tool. Too often, it finds a vertex behind the one I really want, and then gives the wrong angle. Also, it would be nice if the leader text were anchored so you could reposition the text. Fianlly, a config option to limit the number of decimal places displayed. Thanks, CB.
