Tom,

I really haven't had to resort to that level, as I created most of my
objects with polygons - so I can tag the entire object and "move" it with
said tag. Again, what I have is working fine, I just found myself wishing I
could move vector-type objects to an absolute canvas coordinate (quickly).
Since we have the ability to move (vector based) objects *incrementally*, it
just seems that there should be a similar command to move (vector based)
objects to an *absolute* position (other than iterating through all points
and modifying them using "coords"). Obviously, there are some issues with
this, such as vector objects don't generally have an "anchor" position.

Anyway, I don't have strong feelings about this - it just seems to be a
"missing" functionality.

Jeff
