I would love to be able to switch to this app from Calendar feed. From the short periods when I have tested this one it seems much more stable. But the thing that is holding me back is that I don't like how it looks. Reading that it will soon be able to aggregate more is great (I only want one item shown). The other thing I don't like is how it treat "All day" events which I commonly use. They show "23:59" as time in aggregate view and "00:00" without aggregation, why?
Another minor annoyance is that it says "All day: " when I would prefer no text at all.
Sometimes the spacing between the items shown are uneven, not sure what causes this though.
If therefore is not necessary a change of the default calendar application, it would be wonderful if such a repetition, including ringing, would be possible by organizer feed. I mean the slide in the notification window that allows you to close, open or postpone an event.
