Click to jump, or copy a section link when one is available. • Keep Crumbs tucked into a narrow rail, expand it on demand, or pin it open. Dock it on either side and choose which jump buttons and shortcuts to show. 💬 Find your way back in ChatGPT • Browse questions, answers, and headings within answers. Search the conversation outline and jump back to a message. • See question times when available. Approximate times are labeled, and you can disable local timestamp recording or clear saved times. • Use Jump to Top or Jump to Bottom to move through the conversation pane. Older messages may need to load before you can jump to them. 📝 Read Markdown • Switch between Rendered and Raw while keeping heading navigation. • Read tables, task lists, highlighted code, Mermaid diagrams, and math. Wrap long code lines or zoom into diagrams. • Copy the original Markdown from either view. Expand YAML front matter separately when you need it. 🔍 Explore JSON • Switch between a collapsible, syntax-colored tree and the original Raw response. • Search keys, values, and paths, even inside collapsed branches. Group repeated fields and jump between occurrences. • Copy the full response, individual values, property pairs, or paths. 🎨 Make it yours • Choose Glazed to adapt to the page, or Plain for a solid Light, Dark, or System theme. Pick from six accents. • Control which sites show the outline and when Markdown and JSON render automatically.
