Smart Fold

Smart Fold is a highly optimized and lightweight Obsidian plugin that provides advanced yet intuitive tools for efficiently folding Markdown sections. It gives you finer control over the built-in folding mechanism in Obsidian without taking over your content.

Features

Adaptive Fold/Unfold Shortcuts: You can add hotkeys to globally increase or decrease the headings' folding depth across the active document.

Specific Heading Level Toggles: Easily toggle specific heading levels from H1 to H6 individually. Hotkeys can be set for targeting specific levels directly.

Smart Fold: An intelligent command that specifically toggles folding for all headings that do not have any children (sub-headings). Excellent for cleanly summarizing documents where leaf-node contents get too long.

Auto-Fold on Open: Highly requested feature—configure the plugin to automatically apply a specific fold state whenever you open a new file. You can choose to automatically fold everything to H1, or apply the Smart Fold!

Ribbon Quick Icons: Provides quick, aesthetic custom SVG icons on the left Ribbon menu H1-H6, HS (Smart Fold), H+ (Increase Fold), and H- (Decrease Fold).

Unified Toggle Logic: Turning off a ribbon icon in the plugin's settings will automatically disable its corresponding command and hotkey. This keeps your command palette and hotkey list clean and focused only on the 9 core features you use.

Usage & Settings

1. Enable the plugin under Community Plugins.
2. Under Settings -> Smart Fold, you can choose which Ribbon Icons you want visible.
3. You can set the Default Fold State on Open from the same panel.
4. Go to Obsidian's native Settings -> Hotkeys and search for Smart Fold to assign customized shortcuts.

Development

The project requires Node.js >= 24.11.1. You can install dependencies and build it using:

npm install
npm run build
