Lots of special tools. I&#x27;m working on revising them so we can open-source the parts that are useful for general reading.<p>Right now it&#x27;s a Chrome extension, but I&#x27;d love to serve it as plain JS. Anybody know if you can give a web app privileges to open and close tabs without making it a browser extension?<p>(Don&#x27;t worry, btw; if we ever publish this it will be entirely opt-in.)
