Is it possible to add the following functionality to calendars in Confluence?:
> 1. View full calendar year.
> 2. Toggle view among Day/Week/Month/Year from macro.
> 3. Add color coding for specific items without using different calendars for each color.
> 4. Toggle view of various groups off/on from Macro (much like the option available through the "my calendars" view).
> 5. Enable edit permissions without delete permissions so that users can add/remove events but not accidentally delete the calendar.
