First, I'd like if whatever options we discuss also
involves the other transformations with constraints
(scale and grab) so as to keep things as uniform as
possible and as useful as possible in all cases.

This could be a problem for people using the menu to
initiate the transformation.

I'd like to see such a case, the current system was
made to minimize the motion needed to choose an axis
while still allowing the quick selection possible
before (that is, move a bit along the X axis, press
MMB and it's constrained to the X axis).

This was a problem from the start. At the time, I
decided not to do anything about it because there
wasn't any exceptional behavior (different from
drawing at center that is) that seemed fit for all off
screen drawing cases.

In the translation (and scaling) case, yes. In the
rotation case, IMHO, it helps visualize the axis of

Drawing with reduced opacity is certainly an option.
The Alpha value could just be added in the theme (with
sensible default).

That is good too, although I'd prefer if visible
constraint axis could still be possible (I think
they're a bit more user friendly), so it could be a
user option.

As Bassam said, this would be a problem for crowded
scenes (and obviously edit mode on bigger meshes too).

A solution would be to draw in 3 passes (from front to
back): Selection (what is being transformed),
Constraint Axis, Rest of the Scene/Mesh.

Not sure how viable that is though...
