Good to hear you are implementing to-do's without due dates. I currently have both Organiser Feed and Calendar Feed both installed, because for now, Calendar Feed does show to-do's without due dates. But Organiser Feed overall is better, I'd rather just have one.

Also, it would be nice if more aggregate options were given. Such as "aggregate only to-do's without due dates" or "aggregate all to-do's, nearest due dates at top" etc etc

With even more customization on top of that, such as integrating to-do's WITH due dates into the regular stream of events/to-do's.

Sounds like I'm asking for too much. But I'll be glad to donate too. PM me with your PayPal address
