ScrollLess is a Chrome extension that optimizes your ChatGPT browsing experience by allowing you to hide responses with a single shortcut. The tool makes it easy to revisit specific questions and answers by hiding the rest of the conversation. Users can toggle all responses' visibility using the `Ctrl+Shift+Y` (Windows) or `Cmd+Shift+Y` (Mac) shortcut, or manage individual responses by clicking directly on the prompt. Additionally, users can set the extension to auto-hide responses upon loading the conversation, streamlining the search process.
