I'd appreciate the following enhancements to the calender:

- The ability to clone (copy-paste) calendar events.
- A way to classify appointments as tentative, completed, and cancelled.
- Setting preferences for all new events, like "no alarm", a default start time etc.
- A week view that shows the entire day, if that can be done, or another way of listing such that all events on a day are visible without having to scroll the screen.
- A choice to enter dates and times using the keyboard instead of scrolling through the numbers and tapping them on the screen.
