basicly "dude", the "chatheads" are themselves little popups because you know they block a portion of the app content and are by extension a distraction.
I also don't get your point about convenience, how it less convenient to swipe down than it is to swipe to the left to reveal the "chatheads", in both cases followed by selecting the notification?
The point of the notification drawer is that it allows the user to decide when he/she wants to take action on a notification.
Granted the way the notification center works now with switching apps isn't the best way which is why I absolutely love the overlay window functionality of the implementation in the video.
It's funny how most of the iOS users really wanted the android way of notifications and now it seems that we really want their distracting popups...+Paranoid Android
will it be possible to use the overlay windows without "chatheads", i.e. from the notification drawer only?
