Priority of drawing: "Bring Forward" ability so the user can display calendar events that are hidden behind other events
Have a "bring to the front" and/or "bring forward" option (similar to the drawing options in Microsoft documents) on calendar events. If you have more than four overlapping events some get hidden or others have their ends hidden. With a bring forward option the user can arrange the display to best show their calendar.

With this feature, the events in each calendar (or task list) would always appear at the same place in the month view, the agenda view and the widget. For example, my "names" calendar would be on the first place for every day, the events from my "work" calendar would come next... Same with my tasks. And I would be able to specify if the calendars should be shown before or after the tasks.
In week view, I have parallel events set to display as "indented but overlapping".
Often I want to see the details of the event which is "behind", but when I tap on the event it is opened for editing, which is not what I want.
I would prefer it if the "behind" event was just brought to the front, so that it can be seen.
Then, if I tap it again, it could be opened for editing. If course an event which is already on top would be opened on the first tap.
