Fwd: expiring logbook

[Samuel Wales]

just wondering out loud what is usually done here.  open ended.

in principle one could sort in agenda by logbook size and have it show
the 20 biggest.

one could have a command to show logbook [in case any relevant notes
worth saving]
then ask user whether to archive.  archiving would consist of the
header prepended by "=logbook=" or so.  body = logbook.

idk.  not sure i want to keep logbook in agenda files at least for
some entries.  much of this is for speed and size.  some of this is to
eliminate clutter of low-value inactive timestamps for later timestamp
agenda ["daily/weekly"] with log mode.
