Problem:

The "n Watchlist Alerts" (n being a number) text that appears in the top-right corner will not go away until a user have clicked through all the pages that's been changed. A problem arise when there's a lot of items in the watchlist and a user does not have the time to click through sequentially to a point where he/she lost track of which pages left unclicked. This would result in the "n Watchlist Alerts" text displayed all the time.

Solution:

1. Highlight unclicked items in the watchlist alerts page, much like how new (unread) messages is highlighted. Upon clicking, remove the highlight.

2. Perhaps there should be an option to set a user-defined period for alerts expiration. Or it can take the form of "Mark all alerts as read/checked/clicked".
