Got it.

Wow, thanks for such a thorough review.

I can only get it to constrain to the global axes. I link to
http://wiki.blender.org/index.php/Doc:2.6/Manual/3D_interaction/Transform_Control/Axis_Locking
, which mentions this feature -- but since this page is about the Transform
Orientations I think the feature that only works for Global is a bit
off-scope. Agree?

It's on my (eventual) TODO list. The task is non-trivial, though, since it
involves a bit of math and some tricky-to-illustrate points.

The Quaternion rotation mode indeed is there (in part) to avoid Gimbal
Lock, but the Object Manipulator behaves as it does in Local mode. I made
this clearer on the page.

Yep, I was totally wrong.

I meant a second axis ([g][x][x]).  [g][g] does nothing that I can tell,
and [r][r] is one of my faves, Trackball.  So yep, I goofed that up.

Redone.

I implemented the rest of your (excellent) suggestions.

Thank you very much.
