Doable? Yes. But it will probably take some plumbing.
I spent some time trying to get Geeqie to display IPTC metadata (which
is generally embedded in the XMP metadata, iirc), and there was a _lot_
of plumbing to be done. I imagine that changing the EXIF pipeline from
unidirectional to bidirectional would also involve a lot of plumbing.
That said, _should_ it? Unless it's a hack, I imagine it'd take a lot
of UI work to come up with something that's intuitive, easy to use, and
that avoids harming the simplicity of the current EXIF-display mechanisms.
Beyond that, I don't think Geeqie is the right place to do batch
algorithmic EXIF modifications (such as "the EXIF timestamp is off by an
hour; fix that"). That is something that is already supported by exiv2,
and it seems more useful to just build a UI on top of exiv2 than to dump
the functionality into Geeqie.
From exiv2 help:
Actions:
ad | adjust Adjust Exif timestamps by the given time. This action
requires at least one of the -a, -Y, -O or -D options.
