Cleaning New Google Toolbar Feature: Google New Tab Page

Google Toolbar has recently introduced a neat new feature: Google New Tab Page (see description at http://www.google.com/support/toolbar/bin/...561&hl=en.) When I open a new tab, I get a page displaying three features: 9 most visited pages, Recent bookmarks, Recently Closed Tabs. While any of the 9 most visited pages can be removed, it is not possible to clear recent bookmarks used and recently closed tabs (the current solution is to disable and re-enable the feature, but then I lose everything). It would be nice to add cleaning these features to CCleaner. I also wrote to Google toolbar help to have them rectify this, but no response yet.

P.S.: I checked in local settings, Application Data, Google Toolbar, and only the URLs of the 9 Most Visited page are stored there. The data on recent bookmarks is not stored there...
