I'm still dearly wishing it'd be developed further : Sometimes, I set
appointments past midnight (it's, errr, the timezone's fault, I swear), and I'd
rather have them displayed in the agenda on the day before, not to forget about
them in daily view. (Even better, at the bottom of the day.)

I guess it'll wait until I learn something of lisp, but where to start in order
to implement that ?

Kind regards,
William
