I'm a new member so I apologise for referring a quite old post, but it
has a really important issue.
The message is at the following link and was posted by Rich Greenwood
http://grass.itc.it/pipermail/grassuser/2002-November/007837.html
I quote some lines from the message I think are very important:
Also, it would be nice to be able to edit more than one map, or layer, at a time. For example, if I move a parcel line, that line may also define a municipal boundary stored in a different map (or layer). If I update parcel line, I would like to also have the municipal boundary update.
The new ESRI ArcGIS family (but I guess also GeoMedia from Intergraph)
supports this feature for vector data stored in a geodatabase.
What about GRASS? Is it something that is gonna be implemented in the
5.7 version?

My answer is not authoritative at all since I'm new here too (and
Radim Blazek as the main designer of the new vector format would be
the best to tell) but reading the specs for the new vector format one
sees that this new format supports many different categories for a
single geometrical element, meaning that you could tag a single line
both as a parcel boundary and a state/country/municipal etc. boundary.

Yes, it is impossible to edit more vectors at the same time, but it is
possible to have more layers in one vector. There are limits however,
for example, it is not suitable for more overlapping area layers.
