Since this looks like the tech support thread, I&#x27;ll add that<p>&gt; opening and closing those tabs when desired<p>will only work with window.open if the moderation tool&#x27;s window owns the tabs in question. So if you open a HN tab randomly or from another site or wherever, the moderation tool won&#x27;t have opened it, and so it won&#x27;t be able to close it.<p>reddit has RES. People are used to browser extensions, and this doesn&#x27;t sound like it&#x27;d cooperate too well on a phone or similar device, so I say just release the extension.<p>As for fun-sounding feature names, just make a help page in the extension describing how everything works. Maybe call the help page &quot;spoilers&quot; or something. :D<p>Oh and can I be the fourth person to know what Lisp you wrote this in? :D
