Chrome OS will support Picture-In-Picture mode and app shortcuts later this year. Google announced the details along with other upcoming changes to the platform at I/O 2018, making sure to point out that these would just be a couple of the big new additions that Chrome OS (and in turn Chromebooks) would be gaining going forward. Most of the changes referenced will be taking a page out of the Android playbook. Specifically, Chrome OS will be gaining support for the Android IME input, and as part of this Google is looking to make Gboard a supported app on the platform. That would probably mean some of the more recent and popular features would be coming with it, such as in-app GIF search.
Picture-In-Picture mode of course is a feature that Google debuted with Android 8.0 Oreo, and Google says that it'll be introduced to Chrome OS with Android P. To be clear, Google doesn't seem to mention when Android P builds will hit Chrome OS, so the PiP mode could come later if the software comes later. Another Android-based feature coming to Chrome OS will be the above-mentioned app shortcuts. Based on the image these will function just as they do on Android, allowing users to click or tap on an app icon in the tray to bring up shortcuts that will go straight to a specific feature in the app, like composing an email.
Both the Android IME support and the App Shortcuts will be coming to the Chrome OS platform with Chrome OS version 69, which is supposed to be this fall according to Google but there was no exact date mentioned for now. Also coming in Chrome 69 will be support for multi-channel USB, AAudio, and Audio MMAP, which are all directly related to improving the benefits of the already included Pro Audio. Though all of these new features will benefit any Chrome OS user, the Android IME and Gboard support is sure to display the biggest benefits for anyone who picks up a Chrome OS tablet device like the one that was announced by Acer, due to its design being a touchscreen device only.
