I’d really like to see the Your stuff dashboard module to be a part of the admin bar. Somewhere right beside the notifications.
At the moment I’d have to open the dashboard of one of my blogs just to check if there has been a new comment to one of my blogs. I know that a lot of the comments are already shown by notifications as they’re replies to my own comments but e.g. new posts to multi-author blogs don’t fire off a notification.
I imagine some kind of menu like the notifications with icons for “Updated”, “New post”, “new comment”, … instead of the strings.
