Sorting Notifications in Different Categories

It would be great if we had separate notification bars for different stuff. I often get so many notifications at once that sometimes, the important ones get missed. A lot of times, a friend request or a topic reply notification gets lost among other notifications. So it would be great if the notifications were separated. 

The notifications can be filtered into 3/4. 

• Wall Posts (Likes, comments, or someone wrote on your wall) 
• Friend or Relation Requests/ Acceptance Notifications 
• Topic Replies/ Articles 

I feel like if the notifications were sorted in different categories (sort of like Facebook) rather than just all of them in one list, WoP will definitely be easier for me.
