Smart Fold

Smart Fold is a plugin for Obsidian that turns a long Markdown note into a readable outline with one click.

Install: search Smart Fold under Settings → Community plugins → Browse, or add it to Obsidian from the community page.

HS folds every section that has no subheadings, so the paragraphs disappear and the outline stays. Click again to bring everything back.

H1, H2 and H3 fold all headings of one level at once.

H- and H+ fold and unfold one level at a time.

Features

• HS, Smart Fold: folds every heading that has no subheading under it, which are the sections holding the actual text. Parent headings stay open, folds you made by hand are kept, and a second click unfolds the same sections.
• H1 to H6: each toggles all headings of that level. If the first one is folded, all of them unfold, otherwise all of them fold.
• H- and H+: H- folds the deepest level that is still open, and H+ opens the shallowest folded level together with every level above it.
• Fold on open: under Settings → Smart Fold → Default fold state on open, notes can open in Smart Fold or folded to a chosen heading level.
• Native folding: Smart Fold uses the same folds as the arrows next to your headings. Nothing is written into your notes, and any single section opens again with its arrow.

Every action is a ribbon icon and a command, so you can click it or give it a hotkey under Settings → Hotkeys. HS and H1 to H3 are on by default. The other icons can be turned on under Settings → Smart Fold, and turning an icon off also removes its command and hotkey.

Installation

Search for Smart Fold under Settings → Community plugins → Browse, or open its community page, then install and enable it. To install manually, copy main.js and manifest.json from the latest release into <your-vault>/.obsidian/plugins/smart-fold/.
