I think that the QGIS "Add Area" should be renamed to "Add closed boundary"
(or something like that) because GRASS has the "Add Area" tool that in fact
allow you to add boundary and centroid in one go;
another issue I discovered while testing QGIS digitizer with GRASS vectors
is that there is no difference between node and vertex, in GRASS they have
two different "topological meaning"; as it is now you can't tell
where to connect with a new boundary because of this.
