This doesn't seem like it would be that difficult.

d.save does the "save" part now, the "load" would be done by running the
script created by d.save.

I'd love to see this happen.  ps.map offers some of these capabilities
now.  I very much appreciate having ps.map but ps.map is difficult to
learn and use.

Of course we can query now (d.what.sites, d.what.rast, d.what.vect), but
it would be nice to be able to select objects and manage their attributes
interactively.

d.area, d.measure.

That seems like it could be difficult to do.

This sounds like v.digit, integrated more completely into the environment.

I guess I have a shorter list of things I'd like to see done in the near
future.
