Re: UML module hackery

[David Hickerson <dahicke datawest net>]

I have done enough class diagrams in Rat Rose to hate the way they do 
lines, and I am sure that
everyone has opinion one way or the other. I suggest the API 
programmer's approach: "Extend
do not change". Make it an option of the line to behave either way or 
make additional new lines.

There is definely one improvement needed for lines. And that is the 
arrow head needs to also be
manully rotatable. Having the line horizontal and the arrow head 
vertical when connected to a
class because the line is pixel hair off the point of connection is 
pain. Give me a control point for
the rotation of the arrow head.

And I total agree about the labels. Moble like on the interface shape.
