I think that it would be really useful in the GUI to get the maps to be
ordered using natural sort[1]. This would be particularly useful in tools
like `g.gui.animation` where you have to manually order the maps if they
are named with an integer suffix. For example, now, if you have these
maps:
{{{
map_1, map_2, ..., map_10, map_11, ..., map_100, ..., map_200
}}}
when you try to add them using "multiple add" you get something like this:
{{{
map_1, map_10, map_100, map_101, map_102, ..., map_19, map_2, map_20,
map_200, map_21, map_22, ...,
}}}
and this is not usually the animation you intend to create.
Other places where I think that this functionality would also be useful is
things like `Map Layer` in the wxgui and also `g.list`.
WRT to implementation, in python there is the `natsort` package[2] which
is by far the most flexible solution, but it is rather trivial to
implement a subset of the package's functionality on your own (e.g. [3]
and [4]).
