I'm running Blender 2.77 on OS X. I'm following a book that was written I believe for 2.72, and they mention a 'Pie Menu' add on that can be enabled in the UI area of Add Ons in User Preferences. Nothing's listed there, and pressing 'Q' does nothing in 3D view. Am I missing something? Did they abandon this, or is it hidden somewhere? Strangely I can find no documentation on a pie menu in 2.77.
The author seemed enthusiastic about this becoming a default feature in future versions.
