FrançoisBeaufort says in Google+ messages that Chrome OS users can monitor their CPU usage, memory, and zRam statistics in real time in the latest Canary via the new chrome: // sys-internals page. As with all other experimental features, new internal pages for monitoring Chromebook hardware will be available to users on the Chrome OS Stable channel soon. So if you now want to use this feature, you must install Chrome Canary. Otherwise, you need to wait a few weeks to get this feature in the official version.
In addition, Chromebook owners will soon get other cool new features, such as when the local video controls fade out, the mouse cursor to maintain the ability to hide the Chrome operating system to provide a more immersive experience.
