Sync To dos as ical vTodo not vEvents

Having the To Dos appear in my calendar as all day events is OK, but in convenient as they are outside all of my actual To Dos so get ignored. It would be better if they were exportable as the correct ical type - preferably via CalDav, not ICS, so that they can be marked complete when completed, not when I'm in Aha!

Mapping them to proprietary systems like those from Microsoft is not so useful.

I just liked the needed by urgency ;-)
