Microsoft on Wednesday published a new preview build (version 15031) for Windows 10 Insiders that, among other things, adds a new Compact Overlay option that'll allow certain windows to always be shown above any other open apps or windows.
Dona Sarkar, leader of the Windows Insider program at Microsoft, said inbound updates to the Movies & TV app and the Skype Preview app will offer the option to permanently surface those windows above all others.
If you need to pop in to check your e-mail or are actively browsing the web but want to keep watching a show or keep an eye on your video chat, for example, Compact Overlay mode will accommodate without you having to shuffle around windows or add extra displays. Or in other words, it's picture-in-picture mode.
Another new feature, Dynamic Lock, automatically locks your Windows 10 PC when you step away. Leave the office to grab lunch? If your smartphone accompanies you on your journey and is linked to your PC via Bluetooth, Dynamic Lock detect that the phone is no longer in close proximity to the computer and lock it down after 30 seconds.
Other quick-hit changes in the update, which happens to arrive on Windows Developer Day, include a new Share icon and the addition of 52 additional games in full-screen mode with Windows Game Bar. There's also a laundry list of smaller changes, improvements and fixes in Sarkar's post alongside a dozen known issues that persist.
