If you’re loading two or more Subscribe or Bookmark buttons on one page, the load time is about 3x faster in the latest release.
To achieve the faster load times, all Add to Any widgets now use just one menu instance per page, as opposed to loading a menu for each button per page as before. This means that widgets remain in a consistent state from button to button, improving usability. So a search for “Digg” in one Bookmark widget will keep Digg displayed in all the other Bookmark widgets on a page.
Major shoutout to Jeff Levinsky for the browser benchmarks and feedback. Thanks, Jeff!
