I know there's a button for marking all followed posts and pager messages read on the "Your Updates" page, but I would like to see a button that would clear all of the messages. This page gets cluttered for me very quickly, and a clear button would quickly clean it up so I can see important posts quicker/easier.
I really don't like having to click the little X button for each post. which also makes me stop following the post instead of just clearing it from the screen.
Maybe the clear all would still remove the posts, but not make you stop following them so they would appear again.
