[Qgis-developer] more advanced editing tools

[Angelos Tzotsos]

Hi Bernhard,

I agree that some editing ideas are not strictly CAD but we have to 
think the end user and where the tools are expected to be found more 
easily. Also the number of new tools are important. For 2-5 new tools, 
extending cadTools would be more appropriate than a new plugin.
