Read Thread Change Suggestion

One thing I miss from the old system is when I read a thread from the New Posts or wherever, is it possible to change the color or the link to a lighter color after I go back to the list of posts so I don't accidentally re-read them.

Now that I think of it, in the older system, after I read a new post, it disappeared from the list. I think I would have preferred it to become a lighter text back then too.

This may be a simple task to complete for the next update.
