[Orgmode] Finding old appointments

[Tassilo Horn]

Hi all,

for some projects, I have tenth of appointment entry children with a
past timestamp.  They sometimes annoy me cause they make spotting the
actual entries harder.

Is there a way to spot such outdated entries, like building an agenda
view of outdated entries?  To be more precise, with outdated entry I
mean a headline that contains only past timestamps and has only finished
todos and is not tagged with ARCHIVE (cause then I already spotted it).

Maybe that's a task for a custom agenda view?  I have to admit, that I
didn't use those till now...

Bye,
Tassilo
