-### Secondary Menu API
+---
 
-Views can control the secondary (contextual) menu.
+## Secondary Menu API 📋
+
+The secondary menu is a contextual sidebar that appears next to the main content area. It supports **collapsible groups** with icons and badges, making it perfect for:
+
+- **Settings pages** (grouped settings categories)
+- **File browsers** (folder trees)
+- **Project navigation** (grouped by category)
+- **Documentation** (chapters/sections)
+
+### Collapsible Groups
+
+Groups can be collapsed/expanded by clicking the group header. The state is visually indicated with an icon rotation.
 
 ```typescript
-// Set menu
+// Set secondary menu with collapsible groups
 appui.setSecondaryMenu({
   heading: 'Settings',
   groups: [
     {
       name: 'Account',

+        { key: 'profile', iconName: 'lucide:user', action: () => showProfile() },
-        { key: 'security', iconName: 'lucide:shield', action: () => {} },
+        { key: 'security', iconName: 'lucide:shield', badge: '!', badgeVariant: 'warning', action: () => showSecurity() },
+        { key: 'billing', iconName: 'lucide:credit-card', action: () => showBilling() }
+      ]

       ]
     }
   ]
 });
+```

+### Secondary Menu Item Properties

+// Visibility control
+appui.setSecondaryMenuCollapsed(true);   // Collapse panel
+appui.setSecondaryMenuVisible(false);     // Hide completely
+
 // Clear
 appui.clearSecondaryMenu();
 ```
 
-### Content Tabs API
+### View-Specific Secondary Menus
 
-Control tabs in the main content area.
+Each view can define its own secondary menu that appears when the view is activated:
 
 ```typescript
-// Set tabs
+// In view definition
-appui.setContentTabs([
+{
-  { key: 'code', iconName: 'lucide:code', action: () => {} },
+  id: 'settings',
-  { key: 'preview', iconName: 'lucide:eye', action: () => {} }
+  name: 'Settings',
-]);
+  content: 'my-settings-view',
+  secondaryMenu: [
+    {
+      name: 'General',
+      items: [
+        { key: 'account', iconName: 'lucide:user', action: () => {} },
+        { key: 'security', iconName: 'lucide:shield', action: () => {} }
+      ]
+    }
+  ]
+}
 
-// Add/remove
+// Or set dynamically in view's onActivate hook
-appui.addContentTab({ key: 'debug', iconName: 'lucide:bug', action: () => {} });
+onActivate(context: IViewActivationContext) {
-appui.removeContentTab('debug');
+  context.appui.setSecondaryMenu({
-
+    heading: 'Project Files',
-// Select
+    groups: [...]
-appui.selectContentTab('preview');
+  });
-
+}
-// Get current
-const current = appui.getSelectedContentTab();
 ```
 
-### Activity Log API
+---
 
-Add activity entries to the right-side activity log.
+## Content Tabs API 📑
+
+Content tabs appear above the main view content. They're designed for **opening multiple items** from tables, lists, or other data sources—similar to browser tabs or IDE editor tabs.
+
+### Common Use Cases
+
+- **Table row details** - Click a row to open it as a tab
+- **Document editing** - Open multiple documents
+- **Entity inspection** - View customer, order, product details
+- **Multi-file editing** - Edit multiple configuration files
+
+### Closable Tabs
+
+Tabs can be closable, allowing users to open items, work with them, and close when done:
+
+```typescript
+// Set initial tabs
+appui.setContentTabs([
+  { key: 'overview', iconName: 'lucide:home', action: () => showOverview() },
+  { key: 'activity', iconName: 'lucide:activity', action: () => showActivity() }
+]);
+
+// Add a closable tab when user clicks a table row
+table.addEventListener('row-click', (e) => {
+  const item = e.detail.item;
+
+  appui.addContentTab({
+    key: `item-${item.id}`,
+    label: item.name,                      // Display label
+    iconName: 'lucide:file',
+    closable: true,                        // Allow closing
+    action: () => showItemDetails(item)
+  });
+
+  // Select the new tab
+  appui.selectContentTab(`item-${item.id}`);
+});
+
+// Handle tab close
+appui.addEventListener('tab-close', (e) => {
+  const tabKey = e.detail.key;
+  // Cleanup resources if needed
+  console.log(`Tab ${tabKey} closed`);
+});
+```
+
+### Tab Management
+
+```typescript
+// Add/remove tabs
+appui.addContentTab({
+  key: 'debug',
+  iconName: 'lucide:bug',
+  closable: true,
+  action: () => {}
+});
+appui.removeContentTab('debug');
+
+// Select tab
+appui.selectContentTab('preview');
+
+// Get current tab
+const current = appui.getSelectedContentTab();
+
+// Visibility control
+appui.setContentTabsVisible(false);        // Hide tab bar
+
+// Auto-hide when only one tab
+appui.setContentTabsAutoHide(true, 1);     // Hide when ≤ 1 tab
+```
+
+### Opening Items from Tables/Lists
+
+A common pattern is opening table rows as closable tabs:
+
+```typescript
+@customElement('my-customers-view')
+class MyCustomersView extends DeesElement {
+  private appui: DeesAppui;
+
+  onActivate(context: IViewActivationContext) {
+    this.appui = context.appui;
+
+    // Set base tabs
+    this.appui.setContentTabs([
+      { key: 'list', label: 'All Customers', iconName: 'lucide:users', action: () => this.showList() }
+    ]);
+  }
+
+  render() {
+    return html`
+      <dees-table
+        .data=${this.customers}
+        @row-dblclick=${this.openCustomerTab}
+      ></dees-table>
+    `;

+## Activity Log API 📊
+
+The activity log is a slide-out panel on the right side showing user actions and system events.
+
+### Activity Log Toggle
+
+The appbar includes a toggle button with a badge showing the entry count:
+
+```typescript
+// Control visibility
+appui.setActivityLogVisible(true);     // Show panel
+appui.toggleActivityLog();             // Toggle state
+const isVisible = appui.getActivityLogVisible();
+
+// The toggle button automatically shows entry count
+// Add entries and the badge updates automatically
+```
+
