Microsoft is testing a new feature for Edge Dev and Canary that allows you to easily switch profiles within a progressive web app. The browser already supports profile switching, but this addition brings the option to "installed" PWAs.
Microsoft is putting a lot of weight behind progressive web apps (PWAs), and it offered a peek at some of the improvements it's making in a session at Build 2020. Overall, the company is looking to make some big changes that result in PWAs feeling much more like native apps on Windows and other platforms.
Progressive web apps are perceived to be Microsoft's best chance of eliminating its app gap. Unfortunately, Microsoft's partnership with Google in developing PWA standards may help Google make Chrome and Android a greater threat to Windows.
