After removing the lists feature,
Google Bookmarks updated the interface to match all the other Google services. It's nice to see that Google Bookmarks still exists, but the service only integrates with Google Web History and Google Toolbar for Internet Explorer. The integration with Google search has been removed, now that Google focuses on Google+, and the Android ICS browser uses the bookmark sync service from Chrome.
Google will have to find a way to merge Google Bookmarks with Chrome's bookmark sync. Google Toolbar could show the bookmarks saved in Chrome, while Google Bookmarks could be a web interface for Chrome's bookmarks. Unfortunately, Chrome uses folders, while Google Bookmarks uses labels, so merging the bookmarks is not an easy task.
