Fantastic job on the calendar, I'm still working on modifying everything to my liking but enjoying it so far. As stated by other users a day/week/month tab would be very nice to have.
Also, I was curious how you created the calendar in your screenshots tab, I really liked the "mini" calendar w/ just the dates and days of the weeks S/M/T/W/Th/F. I just can't seem to figure it out. Anyway great job on the project so far and best of luck on further releases!
