Too bad the toast notifications aren't like the calendar toast notifications. They persists until you act on them, and they have interaction as a part of them. ****, if size is a problem you could make them small like they are now, and pull down to expand them. Maybe have a little number somewhere to denote how many notifications are waiting. Clear one, and the next appears.

edit: ahaha the board automatically censored my cuss word, which was hardly a bad one (the opposite of heaven)
