We are introducing a new notifications feature to allow users to select what notifications they would like to receive when subscribed to a group. This will give more precise notifications of posted content within the group.
Also We are updating the notifications functionality to include a mark all as read option within the notification page. Lastly we looking to update the notifications dropdown menu which will have a filter function to more easily click through notifications based on their function for example, Group, mentions, connections and not to mention the existing All and Unread.
