 map, your virtual map gets modified also (just like a database view). You
 then don't have to run v.extract each time.

 IMHO that would ease heavy vector analysis a lot. I'm often using this
 approach in some other GIS software ;o)

 >Also, you might consider it useful to avoid clutter if you can list views
 separately from vector maps (i.e. g.list view).

 good idea

 at least me being lazy and wingrass-GUI-oriented would be happy
