Observed behavior
I like that events are shown within the photo Stream. But for some reason they are shown at the end of each month. I would expect them to show up within each month at the position where they happened (according to the date of the first photo of the event)
Example:
I have taken daily photos through the whole month. I now sort photos from the 7th and 8th into one event. I would now expect the event to be shown in the stream directly between the photos 7th and 8th.
