<p><strong>Collapsi for the Block Editor</strong> adds an editor-only chevron toggle to every Gutenberg block. Hover any top-level block, click the chevron, and the block tucks away into a compact bar showing the block’s icon, title, and a short content preview (paragraph text, image alt, “5 blocks”, and so on). Toggle it back open with the same chevron.</p>
<p>Built for the long pages and Site Editor templates where scrolling past 50 blocks to find the one you want is the daily annoyance. Collapsi is <strong>strictly editor-only</strong> — your published site is untouched, no extra CSS or JS ships to the frontend.</p>
<h4>Why this plugin</h4>
<ul>
<li><strong>Stop scrolling endlessly.</strong> Collapse the sections you’re not working on. Find the one you are in seconds.</li>
<li><strong>Works on every block.</strong> Core, third-party, custom, ACF — anything Gutenberg renders, Collapsi can collapse.</li>
<li><strong>Survives reloads.</strong> Collapse state is saved per post, per template, per browser. Come back tomorrow, your layout is where you left it.</li>
<li><strong>Per-instance opt-out.</strong> Set “Never collapse this block” on a hero or any pinned block from the block settings menu.</li>
<li><strong>Keyboard shortcut.</strong> <code>Alt+Shift+C</code> toggles all top-level blocks at once. Discoverable in WP’s shortcut help modal (<code>?</code>).</li>
<li><strong>No telemetry. No remote calls. No premium upsell.</strong> Free, GPL, forever.</li>
</ul>
<h4>How it works</h4>
<p>The plugin hooks <code>editor.BlockListBlock</code> with a higher-order component that wraps every top-level block. State lives in a <code>@wordpress/data</code> store and persists to <code>localStorage</code> keyed by either the block’s structural path (<code>"0.2.1"</code>) or its user-set name from Gutenberg’s rename feature. A <code>PluginSidebar</code> exposes Collapse All / Expand All / Focus Mode. Settings live at <code>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Collapsi</code> and persist via the REST API.</p>
<h4>Compatibility</h4>
<ul>
<li>WordPress 6.5+ (iframed editor)</li>
<li>PHP 7.4+</li>
<li>Post Editor and Site Editor</li>
<li>Browsers: Chrome 90+, Firefox 88+, Safari 14+, Edge 90+</li>
</ul>
<h4>Not in scope</h4>
<ul>
<li>No Classic Editor support — Gutenberg only</li>
<li>No frontend collapse (this is an editor productivity plugin, not a UX framework)</li>
<li>No premium tier</li>
</ul>
