4chan-X is a userscript and browser extension that enhances the browsing experience on the imageboard 4chan. It introduces numerous features such as inline post expansion, quick reply boxes, thread watching, and customizable filtering to streamline navigation and participation. The tool allows posts and threads to be hidden or highlighted based on keywords, IDs, or poster attributes, giving users more control over the content they see. It also provides auto-updating of threads, inline image expansion, and keyboard shortcuts to improve efficiency for heavy users. The extension is highly configurable, offering theme options, interface tweaks, and feature toggles so individuals can tailor the experience to their preferences. Over time, 4chan-X has become the de facto enhancement suite for users who want more functionality and usability beyond the default 4chan interface.
