as an aside, just wanted to point out an alternative that i use
exclusively instead of date trees.  of course it is not for everybody
and i do not want to hijack the thread, so followups should have a
different header.

  ***** CONVERSATION [2017-01-15 Sun 14:09] talked with carsten

i sort these in the outline.  they are always visible at the bottom of
every subtree, in time order.  i can follow a thread by just reading
the headers.  i can quickly do a binary search to find a date.  i can
select a region without selecting parents.  they show up nicely in the
agenda.  i sort them in the agenda also.  links to them work fine.
the date information i need is there without changing visibility, yet
unobtrusive.

it might sound silly to bring it up, but everybody i have told to this
has had an aha moment and been enthusiastic.

just as an aside.
