Reddit Enhancement Suite is a browser extension that injects JavaScript and CSS directly into the Reddit web interface to customize its layout, styling, and behavior. It operates entirely on the client side, storing user preferences locally and manipulating the page's DOM to rearrange elements, apply visual overrides, and observe mutations so that modifications persist even as new content loads dynamically.
The extension provides keyboard-driven navigation for browsing posts and comments without a mouse, along with user-defined filtering that can hide or highlight comments and posts based on rules like keywords, vote scores, or author names. It also enables inline display of linked images and media content directly within pages, and allows users to assign custom labels or notes to usernames for personal reference across the site.
Additional capabilities include tracking and displaying a user's voting and posting activity for contextual reference, as well as adjusting the visual layout and styling through configurable themes and display options. The extension is distributed through browser extension stores and can be installed directly from the project's documentation page.
