(Normally I don't like offering ideas for free)

Since Calendars are available for the iPhone I desperately am looking for one, that shows the bars for whole-day events in the week-view not blocking the whole day but from starting time to the end time. In your Icon for your product it is like that but your calendar - as I can see in the screen shot - does it like all the others do.
For most of my entries are long-term events it's always kind of iffy...

If my english doesn't make my idea clear to you, here's an example:
I am away from Friday 18:00 until Sunday 12:00 and from Sunday 18:00 till Monday 15:00 is another event. The bar in the week view should now begin in the field for Friday in the last quarter and end in the field for Sunday in the middle for there is enough space to let the next bar start at the last quarter which lasts till Monday in the middle (to be exact: middle plus 1/8...)

Now the bars do not need two lines and the events do not overlap!

This would just be great! I like your design of your product very much! And if you can offer this on top, you'll need a new category like "all stars plus one"...
