Google is rolling out "Managed User" settings in the latest build of Canary / Chromium letting user to modify their own settings and privileges, without any interference from other users. In short, the feature allow creation of "less-privileged user accounts in Chrome" as oppose to the current, "where all Chrome users can set up multiple user profiles and sync them together in the browser." This allows personalized settings for each user, even on a shared device as per his requirements.
Once the new feature is implemented, users will be able to create less-privileged users. Managed users will only have restricted and pre-configured access to browsing that the Chrome root user thinks appropriate.
The root user (or, the first user) can also disable incognito mode for the managed users. As this feature is not complete yet, we don’t have much details about it.
To check it out yourself, download the latest Chromium / Chrome Canary build here, with -enable-managed-users switch, and visit the chrome://settings/managedUser page. Type the following through Terminal.app on OS X and on Windows through the File Explorer:/Applications/Google\ Chrome\ Canary.app/Contents/MacOS/Google\ Chrome\ Canary -enable-managed-users -managed
Once you've done that, type "chrome://settings/managedUser" into your Canary address bar to access the new user management pane.
Here is a screenshot that shows the features:
Update 12/09: In addtion, Google also plan to roll out Google Now integrated with Chrome, as the references in the latest Chromium for Mac build hints to Google Now's features appearing in Google Chrome's notification cards.
"This is huge news: Google Now is going to be integrated into Google Chrome. Basically, Google Now Cards will appear in Chrome via Chrome Notifications," posted François Beaufort in a G+ post.
"Creating a skeleton for Google Now for Chrome implementation. The CL creates the top-level structure for showing Google Now cards in Chrome via Chrome Notifications.
The implementation lives behind -enable-google-now-integration flag," reads the Chromium Code Reviews post.
However, it's not clear how long it will take for the new feature to roll out.
