Or at least add tasks from the calendar. Right now, the functions (and usability) are fairly separated. Notes are nice (for things like holidays and birthdays), but most folks need event scheduling. Tasks are the closest thing to that in Osmo.
BTW, I compiled the SVN version. Horizontal is nice.
If you manage to make Osmo easy to sync, and make an event calendar (with interlinking between calendar, tasks and contacts) you will have the best PIM app on linux.
