Notifications need to be more obvious - a banner or stronger pings when a new comment is made- items can go hours without being seen.
Notifications are very weak within the platform. I can go hours and sometimes days without realizing a comment has been added or new discussion post has been made. I have all notification options available turned on and still do not receive banners or emails fro some reason. The system should offer levels of notification where it can almost be an annoyance if you have an unread item. If this tool is supposed to be a one stop shop for communication within your team everything should be done to avoid missing new messages. As it stands currently this is the biggest reason I don't use this system for all correspondence that it should be able to handle.
