That's the smallest issue. gtk_launch_uri() is your friend here and in
theory also supports Thunar.

I kinda doubt that Thunar adapted GIO metadata (which is where nautilus
saves this stuff now) support so fast, as it's only in nautilus since
Not sure if Thunar has the sort order available for others somewhere,

The sorting work would need to be done in eog-list-store.c. Sorting
happens through the eog_list_store_compare_func() function. It currently
sorts by filename. If you don't have that much time, it would help
already if you could modify it to sort by mtime (GIO/GFile will have
this info) and check if any function in eog seems to rely on the old
sorting behavior and breaks with mtime sorting. If that's not the case
the rest shouldn't be a big problem.

Extending the plugin API to be able to do this, wouldn't be trivial as
you'd have to adapt most of the eog GUI code to be pluggable as well.
It's likely to be error prone too, since eog is a bit fragile in some
Regarding the Scheme bindings, I'm not paticulary against it. But we
would need someone with guile knowledge to make it (and maintain it) as
neither I nor Lucas or Claudio (feel free to correct me guys) know
Scheme well enough. ;)
The current Python bindings are a bit behind for the same reason.
