Google recently announced a new tweak to Chrome OS that will enable easier multitasking for Chromebook users. The new “docking” feature allows small windows like Hangouts and Google Keep notes to be pinned to one side of the screen, much like the “snap” feature found in Microsoft’s more recent Windows releases. Docked windows will remain visible at all times, causing other apps like the Chrome browser or Gmail to be resized.
The feature is a little-publicized addition to the most recent Chrome OS update released the end of last week. You can get the latest Chrome OS build by simply rebooting your Chromebook.
