[Qgis-developer] more advanced editing tools

[Leyan]

Regarding the workflow you described at the end, do you know about 
"avoiding intersection" ?

This is much easier to use than snapping points, and it works across 
different layers.

Regarding the more advanced digitization features, I think the best 
would be to improve CAD tools instead of creating yet another plugin 
that people will not find. I agree that these features are important. 
One I would like is to see the distance and angle directly during 
digitizing, while you enter a line.

Regards,

Leyan
