Like Mozilla Weave that synchronizes almost everything about your Firefox setup; your saved passwords, browsing history, preferences, open browser tabs, and bookmarks across Firefox browsers, new Chromium build now syncs your Chrome Settings and Autofill data together with your bookmarks. As shown in the screenshot above, when setting up Chrome sync you can choose not to include your Chrome Preferences and/or Autofill. In short Chrome Customize-sync gives you ample space todecide on what to sync or not.
This is certainly the beginning of a series of new features that would be added to Chrome. Other features like synchronizing your saved passwords and browser sessions across Chrome browsers are certainly on the way. These features are now present in Chromium Daily Builds, if you want to give it a try.
