Microsoft recently updated Edge for Windows and MacOS with a new feature called ‘Collections’ to help users collect and compare shopping items, combine information from platforms like Wikipedia, and put together your event or research information in a dedicated panel for later reference. The feature is currently exclusive to Chromium-based Microsoft Edge and anyone can test it in the Edge Canary and Dev channels, but you will need to manually it with an experimental flag to get it enabled in Microsoft Edge. Users can also add notes by selecting the add note icon from the top of the Collections pane.
