Skype for modern Windows runs in the full screen mode, but you can easily use other applications alongside Skype with the snap view.
To use the snap view with Skype for modern Windows:
You can easily adjust the snap view. Simply drag the divide bar across the screen until you’ve found your preferred screen size. To exit the snap view, simply drag the bar off of the screen.
When just a small part of the Skype home window is displayed on the screen (see the picture below), the Skype menu switches from the horizontal to vertical view. To see the rest of the Skype screen, use the vertical scrollbar on the right side.
When you slide the splitting bar to left and expand the Skype home window, Skype menu will switch back to its horizontal view. This is useful when you’re browsing the web, for example. You can snap Skype just to a half or quarter view.
