✨ Trailing Fun
A colorful, gamified typing trail for VS Code. Make every keystroke feel alive.
Features
8 Visual Themes — from a smooth Rainbow Wave to Matrix Rain, Burning Fire, and Neon Cyberpunk. Switch instantly from the status bar.
💾 Smart Auto-Save — automatically disables VS Code's files.autoSave while you type. Your file is saved exactly once, the moment the trail animation finishes. This means watching compilers (tsc, webpack, npm watch) are only triggered once per typing burst — not on every single keystroke.
Autocomplete-Aware — works seamlessly with GitHub Copilot and IntelliSense. Skips decoration on massive pastes to keep things clean.
Zero Idle Overhead — the animation engine is fully event-driven. It starts on your first keypress and stops itself automatically when you're not typing.

- Smart Auto-Save: Enabled by default. When active,
files.autoSave is temporarily set to off during typing and restored when you disable or uninstall the extension.
- Performance: The animation loop is fully idle-aware — no CPU or memory is used while you are not typing.
- Ligatures: If characters appear shifted in some themes, try disabling font ligatures for your editor font.
Enjoy the magic! 🪄
