Events like anniversaries and similar that last a whole day (or multiple whole days) should not be printed at the very top at 0:00 in the day view. Instead there should be a special row above the hour-rows that does not scroll away, if you scroll down to the evening hours.

The reason is that -especially on not-high-resolution-screens- you don't always see the whole timetable and maybe don't expect events at midnight (and thus miss the whole-day-event).

In regard to bug 7115, this should probably not color the whole day.

If multiple whole-day-events occur on the same day, the row should automatically increase it's height to fit for all events.
