Gemini Chat Folder & Performance Booster

Zero-lag conversation folding for Gemini using CSS pre-hiding and chunked DOM processing.

🚀 Say Goodbye to Browser Lag and UI Freezes on Google Gemini! Do your Google Gemini chats slow to a crawl or freeze completely when working on large software projects with thousands of lines of code? When conversations grow long, the browser struggles to constantly recalculate and repaint thousands of syntax-highlighted DOM elements every time you scroll, switch chats, or stream a new response. Gemini Chat Folder & Performance Booster solves this at the engine level. Using a Dual-Engine Pre-Hide Architecture (`content-visibility: hidden` and CSS strict containment), it freezes off-screen DOM complexity before the browser even attempts to paint it—reducing CPU/GPU layout lag to virtually zero. ✨ KEY FEATURES ⚡ Zero-Lag Chat Switching (Pre-Hide Architecture) Switch into massive, code-heavy conversation histories without the dreaded multi-second browser freeze. Older messages and heavy code blocks are intercepted at `document_start` and processed asynchronously in smooth, bottom-up chunks. 💻 Smart Code Block Folding • Automatically collapses lengthy `<pre>` code blocks while keeping Gemini's native header, "Copy", and "Download" buttons 100% accessible. • Copy or download code with a single click without ever expanding the block! • Displays a clean preview bar showing the first meaningful lines of code, total line count, and size in KB (e.g., `▶ Expand Code • 240 Lines • 6.8 KB`). • Includes a convenient "▲ Collapse Code Block" button at the bottom of expanded snippets so you never have to scroll back up. 🗂️ Intelligent Conversation Folding • Automatically folds older prompts and responses, keeping only your latest active exchange unfolded so you never lose context. • Color-coded compact headers (Blue for You, Green for Gemini) display an instant text summary, code block count, and total line stats (e.g., `2 Code (340 Lines)`). • Instant Fold on Submit: As soon as you press `Enter` or click `Send`, all previous messages and code blocks collapse automatically to keep your workspace clean and fast. 🎛️ Floating Quick-Control Toolbar Located neatly at the top right of the Gemini interface: • Live Counter: Track folded messages and code blocks in real time (`Msgs: 14/16 • Code: 22/22`). • Collapse All / Expand All Code: Manage your entire chat view with one click. • Independent Toggles: Turn `Auto-Code` and `Auto-Msg` folding on or off anytime. 🔒 100% PRIVATE & LIGHTWEIGHT • Zero external servers, zero analytics, and zero data collection. • Runs entirely locally inside your browser tab on `gemini.google.com`. • Built specifically for developers, software engineers, and power users who push Gemini to its limits.
