Sad news, wesgreen. I just hope your "guess" doesn't come from never using Seqretary.

I remember trollo was saying he based Seqretary on Outlook/Korganizer - the only Nokia/Maemo PIM dev to make such great statement. However, not having functionality described in points 1 to 3 is a killer.

Not one PIM app (osmo, kdepimpi, gpe calendar, pimlico, mcalendar) provides grouping functionality!!!
Only kdepimpi does basic category filtering!!!
How can this be???
