I remain humble - I should have known you wouldn't mess up. In that case, obviously, it is a brilliant idea.
On a slightly different note. As I see jotting notes has come up a lot lately, I see that Kontakt (KDE) supports something called JOURNAL that adds to the ics file. I keep all such unorthodox stuff in a separate ics file, but although it doesn't show up in Rainlendar, it is also not changed or deleted by Rainlendar. I am sure you are aware of this, but IF you consider the notes stuff, I would favour the journal entries supported by Kontact (and I hope ics spec). Could be useful, I suppose, although it would hardly be on the top priority list as far as I am concerned.
DESCRIPTION:Dette er en test for å se om det er mulig å bruke journalen
på noen fornuftig måte. Litt om tegnsett\, etc
