JoyReactor Improved - Post Minimizer

This browser extension is for old.reactor.cc and joyreactor.cc.

Allows you to collapse an open long post at any time.

After expanding the post, it adds a button to the site, clicking on which will return the post to the minimized mode, and the page being viewed will return to the same (±) place where it was before the post was expanded. If the opening post is viewed to the end, the button will hide automatically.
In the extension settings, you can specify the location of this button - to the left or right of the post.
