Un-push notifications after I actively read all messages
When I read actively read all messages on a device, the pushed notifications to my other devices should be "un-pushed", meaning they disappear from Android's notification bar and the favicon turns from red to black, for instance.
Since https://mattermost.uservoice.com/forums/306457-general/suggestions/13834386-option-to-push-notify-to-mobile-even-when-logged-i got implemented (which asked for an option but got implemented as the only possible behavior), each notification must be marked as read on each device separately, which is really time-wasting and distracting.

And in iOS update the new message notification (red circle on the app icon), removing when all messages are read or updating the number of new messages.
