Twitter Home shows all updates since login

When visiting the Twitter Home, I think that it should show all of the updates since login/fetch. These should have a sort of different background color or something. There should be a limit of 75 or something. If there are only a few since last login or there are none, then it should show the ones since last login (have the background color different), and then continue with the rest of the list (as usual).
This would help with replies/updates that are meant for a user, but are hidden because there are so many other updates and it is moved to another page.
