Lazo & Rosali - great work and glad to see the cooperation.
I think the full calendar implementation would be great!
Some features that would be nice with the full calendar implementation:
1. year change (for future dates while still in month view)
2. recurring events (for birthdays, etc)
3. expanded event data (title, location, description, tags, categories, etc)
4. shared and multiple calendars
5. event search
Just thinking out loud. Keep up the good work.
