[Qgis-developer] more advanced editing tools

I know "avoid intersection" and it works ok but having several layers as
digitizing base and creating a new polygon it is not very handy (open
menu untick what is ticked, tick what you need now, digitize the
polygon). It seems more straight-forward (especially from a user's point
of view) to copy a polygon from a base layer (e.g. parcels) into your
edit layer, select a polygon/line in another layer, activate your edit
layer again and click on a "clip" button. More convenient would be
Giovannis "fill space" option.
Regarding cadTools I would expect CAD-like functions in there, i.e.
construction things, clipping, saving all layers etc. do IMHO not really
fit to CAD.
Are there any other editTools around?
