Dear Xara...

I appreciate the new flat ends and the balancing of the curve.
All I then see is the underlying code is applied to all Smart Arrows.

You trumpet Smart Arrows 01 to 06 as new.
All they appear to be is the one arrow in a number of states (ends, curvature, dash pattern).
Any can be constructed from any other, including Smart Arrows 12 to 20.
To not have a lock point at flat is careless.
