NotifyClean

清理通知区域

You could configure which apps are allowed to create notifications in the top left area, the notification area. If an app creates a notification it will be collected and added to the list.

You could deny *all* notifications of an app or only *specific* messages - if it's not a customized notification. So I used it to hide "waiting for connection", but not "you are connected".

With a donation you supports this app and get more options.

IMPORTANT

Your device has to be rooted to install the required X-posed framework: http://tinyurl.com/cd46qco
