When I'm in Projects view, there is no number badge next to Home button. However when I go to Home view, suddenly the number of unread notifications appears.
This is not smart behaviour in my opinion, since I mostly care about the number of unread notifications when I'm outside of Home view. Being able to see the number all times was more comfortable, this way I have to go to Home views every all the time to check for new notification.
The bell icon doesn't show number of unread notifications at all. Once again it would be smarter to be able to see the number without actually opening the popup window.
