Calendar Only Template

Notes should provide a simple Calendar Application Template with no email etc.

The calendar should allow for all the standard calendar functionality we know and love with a couple of tweaks.

1.  Sure would be nice if I could have ONE calendar to manage many different categories of information. 

2.  Be able to hide / show different calendar categories

3.  Categories should be color coded

4.  Categories should be able to be restricted by reader / author 

For example, my main business is managing real estate.  We have the need to setup recurring entries for meetings, contracts, project tasks, etc.  I would love to show a list of category check boxes when checked display those calendar entries so I can see if/when things overlap.

Obviously the calendar should be notes client and web / mobile based

Secured with reader / author names

Should be able to get popup warnings for any calendar entries in any calendar OR the ability to click a button to add it / synch it with my personal calendar
