gnus-diary provides new sorting functions (see
Sorting
the Summary Buffer ) called
gnus-summary-sort-by-schedule,
gnus-thread-sort-by-schedule and
gnus-article-sort-by-schedule. These functions let
you organize your diary summary buffers from the closest event to
the farthest one.
gnus-diary automatically installs
gnus-summary-sort-by-schedule as a menu item in the
summary buffer's “sort” menu, and the two others as
the primary (hence default) sorting functions in the group
parameters (see Diary Group
Parameters).
