I agree. of the scale-rotate-translate triad, this only applies to
translation. rotation and scale work great as they are. (scale
especially feels nice). Nonetheless, I urge/request implementing it-
sometimes niceties of interface conflict with cleanliness of design.

hmm. would it be possible to display a ghost "cursor" or transformation
center icon during a move? something with visual similarity to the new
lights display, that indicates the center of transformation and
orientation for multi objects. The simplest form of this could be a
thicker/bolder version of the object center axis being drawn at the
selection/translation center.


A further wrinkle I haven't considered is the other transformation
center modes ( 3D cursor, individual centers, etc.) It seems that these
have not been implented in object mode yet. I still think translation is
a special case for these modes, because it is largely un-affected by
them, whereas rotation/scale change dramatically.
