A useful feature to add to watchlists would be notification of changes to watched pages. This would perform these tasks whenever a page on the watchlist has changed since the last request of the list: 1. Assign a different CSS class to the watchlist link. This can be used in conjunction with wiki-wide CSS or user CSS and JavaScript code to apply different styling when there are new changes. 2. Depending on user preference, display a message similar to the "You have new messages." message when the user's talk page is changed. Would be useful so I can watch my non-busy watchlist of ~186 pages while performing other tasks.
Checking the entire watchlist and scanning the pages on it for changes on each page view is too expensive.
