Microsoft is testing a new sidebar for web apps that might appear in the stable version of the Edge browser. The latest Canary version of the Chromium-based web browser has this feature. It’s not enabled by default, which means it’s still quite experimental.
Microsoft Edge has a section called “Experiences”, where it allows testers to access and enable features that may not be fully ready yet. Microsoft added a flag for the “web app sidebar”. It is disabled by default, but the feature can be easily enabled for evaluation.
The description confirms that the new feature is in development for all major iterations of Microsoft Edge. In other words, Mac, Windows, and Linux users, who prefer using Microsoft Edge, might get the new web app sidebar in the near future.
In its current iteration, the sidebar appears to offer quick access to the search function. As Reddit user Leoparda64-2 discovered, typing text into the sidebar search grabs relevant web links. Incidentally, the feature mentions that its main function is to offer search results. Just like in Bing and Google Search, the sidebar search feature also supports auto-generated suggestions based on typed text.
As the feature is geared towards web applications, it is highly likely that Microsoft may add more functions in the future. But the current iteration essentially mimics Bing. It offers users three tabs: All, Pictures, and Videos. There could be more options like News, Shopping, etc., hidden in the “Options” menu.
