3 springrolls please

Since @staff has a lot on their plate and my pet feature request is unlikely to be addressed in the short term, I decided to do it myself:

You can install this userscript for yourself using Tampermonkey. I've tested in in Chrome and Firefox, and I don't think there's any reason in principle it shouldn't work in any browser that supports reasonably modern APIs.

Here's what it does specifically:

• If you've already seen a chost, it'll collapse it in its thread.

• If you've already seen all chosts in a thread and that thread doesn't have any tags, it'll hide the thread entirely.

• It'll always show you the version of a chost you first encountered, even if you navigate away and come back.

• Information about what you've seen is only stored in session storage, which means it'll be reset every time you start close and re-open the page. (If people want longer-term storage, let me know and I can probably make that happen.)

Give it a shot! Let me know what you think!

I believe you can update the same way you installed it the first time. Improvements include:

• It no longer runs on views where it's not useful, including individual post view, draft view, and compose view. This means you won't get weird issues where a post gets hidden even if you're directly linked to it.

• It will now play more nicely with the "show/hide posts" interstitial that Cohost adds for long threads.

• It will no longer bring the "read more" overlay down over the top of tags if it's showing a thread because it has new tags.

Please enjoy!
