+<b>Introduce Chimera global coordinate system</b><br>
+Tom Goddard<br>
+November 18, 2009<br>
+Add a transformation matrix that describes the position of a new
+"global" coordinate system in the view frame.  This transform would
+change when all models are rotated.  The current model transforms would
+not change in that case.  Currently the "model with lowest id" defines a
+sort of defacto global coordinate system.  New models are opened aligned
+with that coordinate system.  This is very confusing when models are moved
+relative to one another and a newly opened model aligns with an unintended
+model.  In the proposed system the model transforms would only be used for
+relative model motions.  We would know which models have been moved relative
+to the global frame (non-identity model transform).  I believe this would
+make much more sense to the user.

+<b>Show model coordinate axes</b><br>

+November 14, 2009<br>
+Is is possible in Chimera to display a reference frame? if yes, can we display the default one of the software or the one of a 3D structure?
+Would be nice to display 3-axes perhaps in 3 colors as in VMD for any specified model or for
+all models in the common case where they all share the same coordinate system.  Might also
+have option to center axes depiction at center or corner of model bounding box.
