As believed, this will enable users to quickly take notes on their Chromebook computers directly on the lock screen, without unlocking their devices, but we think it will be more useful for other people to leave you messages on your Chromebook when you’re not at your desk. The note-taking on lock screen feature could soon be available for testing in the developer channel of Chrome OS, but rest assured that you’ll be the first to know when it arrives so you can switch your Chromebook to use the Chrome OS Dev channel if you can’t wait until it hits the stable channel, which should happen later this year.
