A recent Chromium build added a new alternative to the about:flags page: an experimental new tab page. The efficient new tab page is a work in progress and it's optimized for touch screens. Right now, it only includes the web apps you've before installed, which can be prearranged in multiple home screens.
"The idea with this touch NTP is to focus (for now) on apps, and make it easy
to position them into pages. You can swipe/drag to switch pages, and press
and hold to lift an app and rearrange it," explains Google.
