We need to be able to point the Kollab Events calendar at a Google Calendar for things already scheduled AND need events created in Kollab to push events to that calendar so users have a unified view of events whether in their preferred calendar app or Kollab.
Use Cases:
Schools who use Kollab as a Social/Announcement Platform who need to schedule one off events like a PTO meeting through Kollab that shows on the annual calendar hosted on Google.
Businesses who use Kollab for internal cooperation and schedule a BBQ through the app but need to make sure that the boss isn't (or is) going to be gone to the annual conference that's on the main company Calendar.
I could go on - seems obvious.
