If you have already installed the Windows 10 October 2018 Update, you may have noticed the new Skype for Windows 10 app that replaced the old UWP version. This new Skype client has just received support for Split View mode, something that Microsoft has been testing with Skype Insiders in recent weeks.

Split View mode is available under the ellipsis menu, and you can turn it on and off at will. Once enabled, the right panel of Skype for Windows 10 will disappear, leaving a narrower window that just includes a list of recent chats. You will then be able to open any conversation you want in separate windows, something that nostalgics of the Skype Classic app should certainly appreciate.
The new version of Skype for Windows 10 looks and works pretty much like the new cross-platform Skype client (Skype v8), though it leverages unique OS features like push notifications or MyPeople integration. If you’re interested in getting early access to new features, including the freshly-added ability to share files from your personal OneDrive, you can join the Skype app preview program right from the “Help & Feedback” menu in Settings.Further reading: Skype
