I'd like to offer a couple of ideas for the notification dashboards:
- Have a way to dismiss them all. Two finger swipe the list to have them all disappear.
- Allow better content preview. For example, display a bit of an email message when it comes in rather than just the subject. Drag the bottom of the dashboard to expand.
- A holding area of sorts. I may want to deal with certain things later and not now, like email messages that I want to respond to later. Instead of dismissing it permanently, let it the notification get put to the bottom of the stack so it can be viewed later.
- While we're on that topic, how about expanding the stack of notifications? Won't work so well for phones, but with the large screen area of a tablet viewing more means getting things done faster.
