Inbox 3.0 (Notifications v3)
1) Grouping similar notifications together and clearing all with one click
2) Dynamic notifications: if you've seen activity (for example new comments in a task view) then we'll remove those notification items automatically
3) Notifications marked as "read" so you can easily see from all views if you have unread activity
4) Snooze notifications and set do not disturb times
5) Easily see which tasks have new activity in all views, so you don't have to go to notifications to know when there's new activity
6) Make Notification Preferences easier: allow users to save settings across teams and allow admins to set preferences for their users.
