First release includes operator to automatically calculate pole angles for IK bone chains.

I've used this add-on for a while now, it does exactly what it says and it does it well. It erases so much headache and guess work from rigging that I'm baffled this isn't an official part of Blender itself, this should be more wide spread.

Saves a couple tedious minutes adjusting pole angles, doesn't clutter the UI, and you can alt+click to do it on all selected bones at once. What's not to love?
