A recent Chromium build added some new options that let you filter content from web pages. A new dialog titled "Content Settings" adds new features for managing cookies, JavaScript content, images, plug-ins and pop-ups.
For example, you can enable an option that clears cookies when you close the browser, a feature that's available in many other browsers. Other features let you disable images, JavaScript or plug-ins for a list of sites. If these settings are exposed via an API, developers will be able to build extensions like NoScript.
I tried to enable some of the new features, but they didn't work in the most recent Chromium build (revision 37221).
