At the very least, let me sync tasks with "No Context" to a catch-all calendar so I don't have to constantly switch between iCal and OmniFocus. I was able to do this with Things and don't see why OmniFocus doesn't have it.

Also, I some times have to share project calendar with a team and prefer to sync tasks by project so they only see what they need to see - don't make me create a new context for that project. Total duplication of effort.
