With dual-screen devices like the Surface Duo expected to be launched this year, Microsoft is trying to ensure that developers can add support for the new form-factor to their websites, apps and services with relative ease. The company has now added dual-screen support to the built-in F12 emulator in Chromium as an experimental feature that can only be activated by a flag.

Microsoft may have shelved its plans to launch the Windows 10X-powered Surface Neo this year, but the company is apparently still on track to launch the Android-powered Surface Duo before the end of this year. Both, of course, are dual-screen devices, which necessitates a significant amount of change to traditional software that were originally designed for single-screen devices.
