Comment 30 for bug 1440111

fyi, what we've implemented for now is the following (in silo 9):
- calendar notifications will vibrate, instead of playing a sound by default. Calendar notifications can be disabled in Settings->Notifications
- calendar notifications will not be displayed for events that you're marked as "Not Attending" (i.e. after google calendar sync)
- calendar notifications will show up in the Notifications menu in case you miss then
- calendar events will remain in the date/time indicator for the duration of the event and not disappear immediately after the event occurs like they current do

After this land, the next step is we plan to implement the extended Notifications panel in System Settings:
https://wiki.ubuntu.com/Notification

This will allow user to choose sound, vibrate, notification bubbles, etc on a per app basis to control notifcations. Once that panel is done we'll cut over Calendar notifications to use it, in conjunction with the work Charles and his team are doing on the notification backend.
