Paolo & Lorenzo & Company,
I took some time to have a closer look. I don't have the time to prepare
new definitions/descriptions for the tools (as I am suggesting below). I
hope that my findings give some answers to the questions asked above.
Attached an html file with my (tomboy) notes!

Kindest regards, Nikos



Functionality
-------------

# tools that work as expected
g.region.save
g.region.zoom
g.region.multiple.raster
g.region.multiple.vector
r.region.region
r.region.raster
r.region.edge
v.in.region
v.mkgrid.region

# tools that don't work
r.region.vector # wild guess: messes up N-S and/or E-W resolution(s)
r.region.alingTo # doesn't do anything



* One important thing is that, after running some *.region.* tool, to
actually see the "change" it is required to hit twice the "Display
Current Grass Region" button (grass toolbar), that is to deactivate and
activate the red grass region box. Maybe this could be a point to
"improve"?

* Most tools have a "Use region of this map" button. It's unclear to me
why the button is next to the map whose region is to be altered (!)

* The "..." button does not offer the selection of multiple
raster/vector maps in the g.region.multiple.* tools



Descriptions
------------

* Most tools just show the "whole" manual as taken from GRASS

* Most tools do just a single thing

* I suggest to keep only single-definitions/sentences as descriptions
for each tool



Bug 1645
--------

Unclear to me. See my comments in trac. Maybe I don't understand the
reported "wish".
