Microsoft released a new build to Windows Insiders in the Fast ring for both PC and mobile. Build 14291 includes Extensions for the Microsoft Edge browser, the ability to pin tabs in Microsoft Edge, and “Paste and go” or “Paste and search” options in the context menu when you right-click on text areas. The video below shows how to install extensions in Edge to gain additional functionality such as translations and mouse gestures. More details are discussed on the Microsoft Edge Dev Blog.
Beyond Edge, the Maps app has been updated with a new UI and the Alarms & Clock app received a new design. Japanese users will benefit from a one-handed kana touch keyboard and support for lined-mode text input with hand-written character recognition.
Microsoft also introduced the Feedback Hub and combination of the Insider Hub and the Windows Feedback apps for PC and mobile to unify where you can leave feedback to make Windows 10 better. Of course, you can leave feedback for the Feedback Hub.
