me too
that is why i filed this feature request
http://bugzilla.gnome.org/show_bug.cgi?id=87966
it is just waiting for someonw with the time and inclination to implement
it, please add comments if you like.

Dia can flip some shapes.  (Flip Horizontal, Flip Veritical, if i remember
from the object menu, middle click) I have thought about this only a
little and i have not looked at the code but a transform is a transform so
i suspect it would not be impossible to add rotate 90, 180 and 270.
Rotation by an arbitrary angle and Free rotation are an entirely nastier
problem.  Please stop me in my tracks if there is an error in my logic.

Obviosly rotation is a feature that people want.  Eventually would the
plan be to improve diacanvas or somehow replace it diacanvas2?
I know that font issues and GTK2 are the main goals for the forseeable
future but i would love to have even a vague idea of what the future plans
might be.
