Once bitter rivals in the browser wars, Microsoft and Google are now cooperating like never before, with a major Chrome feature originating with Microsoft, according to The Verge.

Microsoft recently moved its Edge browser over to Chromium, the open-source rendering engine that serves as the basis for Chrome. Since the move, Microsoft has been responsible for some 1,900 changes and improvements to Chromium, according to CNET.

While many of these changes are under-the-hood, the latest is a very visible one. CNET says “the tab management feature in Edge lets you right-click on a single tab or a group of tabs you’ve selected then send them to a new or different Edge browser window. It’s useful if you like to group related tabs into a single window.”

The feature caught the eye of Google software engineer Leonard Grey and, as The Verge points out, “now Microsoft is helping bring it directly to Chromium and Chrome.” This is an excellent example of the overall benefit that comes from tech companies working together around open standards and open-source software.
