This add-on is perfect for running a web application in a separate browser window as if it were a native app (like a "PWA" for the desktop). On Linux, it's quite convenient to use this add-on with e.g. the Outlook web app instead of https://github.com/julian-alarcon/prospect-mail and the Microsoft Teams web app instead of the Linux client, which crashes a lot. With this add-on, there is no need to install an extra electron-based app that runs in its own little web browser (i.e. electron), when I can just run it in a separate window of my existing browser.
