Enhance your Gemini web UI with persistent timeline navigation, intelligent code collapsing, and dynamic Material You theming. Up and running in less than a minute!
✨ Key Features
- Interactive Timeline Navigation: Stop scrolling endlessly. The persistent timeline automatically maps your entire conversation, allowing you to instantly jump between your prompts and Gemini's responses with a single click.
- Smart Code Collapsing: Keep your workspace clean. Automatically add 'Collapse/Expand' buttons to massive code blocks. Use the floating navigation arrows to quickly jump between different code segments in long responses.
- Enhanced Code Headers: Instantly recognize what you're looking at. The extension detects the programming language of each block, extracts file names directly from the code context, and displays native Material icons in the header.
- Prompt Snippets & Shortcuts: Save time typing repetitive instructions. Create custom shortcuts for your most used prompts. Just type your prefix (like '/') followed by your keyword to expand it.
- Dynamic Material Theming: Make Gemini truly yours. Select a seed color and the extension will mathematically generate a complete, accessible Material Design 3 palette, seamlessly applying it to the entire Gemini interface in both Light and Dark modes.
