Would it be very difficult to implement an option where rather then
splitting the area between the two maps, the same area is shown for both
maps (i.e., mirrored maps). In that option, moving one map would move the
other map too. This makes it easier to see changes between two maps in
detail. In case my explanation isn't clear, a nice example is the MIrrorMap
plug-in for QGIS.
another online example of the idea here:

And IIRC if you look in the addons(?) repo for grass 6 you'll find a tool
developed to update the other frames or xmons + d.redraw as you moved
around the "master" display. Maybe just in the ML archives though, I
forget.
I guess either swipe or full clone with two mouse cursors will be better
for different people in different situations. Depends on the task. See
also the argyle/diamond r.mapcalc overlay trick in the GRASS Book vol.1
(not sure if it is in later editions too).
