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.
