hi sebastian,

actually, i never closed umbrello until after i wrote that e-mail. i guess i 
am in for a surprise when i re-open my project, hehe.

i think you're absolutely right; it would be a huge change. i just took a very 
quick look at some of the classes and it's pretty obvious it would take me a 
long time to do. plus other objects might need some modification, too.

(for instance, in 'dia' for gnome, boundary boxes on objects have anchor 
points where lines will snap to... but nowhere else. i remember this solution 
worked well, so long as you only wanted your line to stick to one of 4 or 6 
places on the object. really you should be able to anchor your line anywhere 
along the object's edge, not the square mask...)

ah well... this has my vote as most needed improvement for the diagramming 
part of umbrello!

thanks again..
mike
