+# Configurable Maximum Windows Feature
+
+## Overview
+
+This feature makes the maximum window limit configurable through the application's settings, addressing the limitation of hardcoded values (50 for Electron, 15 for Web) in the codebase.
+
+## Changes Made
+
+### 1. Core Type Definition
+
+**File**: `packages/altair-core/src/types/state/settings.interfaces.ts`
+
+Added a new optional property to the `SettingsState` interface:
+
+```typescript
+/**
+ * Maximum number of windows/tabs allowed
+ * @default 50 (Electron), 15 (Web)
+ */
+maxWindows?: number;
+```
+
+This property allows users to override the default maximum window limits based on their workflow needs and hardware capabilities.
+
+### 2. Settings Reducer Update
+
+**File**: `packages/altair-app/src/app/modules/altair/store/settings/settings.reducer.ts`
+
+Updated the `getInitialState()` function to include the default `maxWindows` value from `AltairConfig`:
+
+```typescript
+export const getInitialState = (): SettingsState => {
+  const altairConfig = getAltairConfig();
+  const initialSettings = altairConfig.initialData.settings ?? {};
+  return {
+    theme: altairConfig.defaultTheme,
+    language: <SettingsLanguage>altairConfig.default_language,
+    addQueryDepthLimit: altairConfig.add_query_depth_limit,
+    tabSize: altairConfig.tab_size,
+    maxWindows: altairConfig.max_windows, // NEW
+    ...initialSettings,
+  };
+};
+```
+
+This ensures that the default value from `AltairConfig` (50 for Electron, 15 for Web) is used unless overridden by the user.
+
+### 3. Window Switcher Component
+
+**File**: `packages/altair-app/src/app/modules/altair/components/window-switcher/window-switcher.component.ts`
+
+Changed `maxWindowCount` from a class property initialized with `AltairConfig` to an input signal that receives the value from settings:
+
+```typescript
+// Before:
+maxWindowCount = this.altairConfig.max_windows;
+
+// After:
+readonly maxWindowCount = input(this.altairConfig.max_windows);
+```
+
+This allows the component to reactively update when the setting changes.
+
+### 4. Header Component Template
+
+**File**: `packages/altair-app/src/app/modules/altair/components/header/header.component.html`
+
+Added the `maxWindowCount` binding to pass the setting value to the window switcher:
+
+```html
+<app-window-switcher
+  [windows]="windows()"
+  [windowIds]="windowIds()"
+  [activeWindowId]="activeWindowId()"
+  [closedWindows]="closedWindows()"
+  [isElectron]="isElectron()"
+  [collections]="collections()"
+  [enableScrollbar]="settings()?.enableTablistScrollbar"
+  [maxWindowCount]="settings()?.maxWindows"  <!-- NEW -->
+  (newWindowChange)="newWindowChange.emit($event)"
+  ...
+/>
+```
+
+### 5. Internationalization
+
+**File**: `packages/altair-app/src/assets/i18n/en-US.json`
+
+Added a translation key for the setting label:
+
+```json
+"SETTINGS_MAX_WINDOWS_TEXT": "Maximum Windows"
+```
+
+### 6. Tests
+
+**File**: `packages/altair-app/src/app/modules/altair/store/settings/settings.spec.ts`
+
+Updated all test cases to include the `maxWindows` property in the mock configuration and expected results:
+
+- Added `max_windows: 15` to the mock `AltairConfig`
+- Updated all test expectations to include `maxWindows: 15` (or `maxWindows: 50` for Electron tests)
+
+## How to Use
+
+### For End Users
+
+1. Open Altair GraphQL Client
+2. Navigate to Settings (gear icon in the header)
+3. In the settings JSON editor, add or modify the `maxWindows` property:
+
+```json
+{
+  "theme": "dark",
+  "language": "en-US",
+  "maxWindows": 100,  // Set your desired limit
+  ...
+}
+```
+
+4. Click Save
+
+The new limit will take effect immediately, allowing you to open more (or fewer) windows based on your preference.
+
+### For Developers/Integrators
+
+When embedding Altair or initializing it programmatically, you can set the initial maximum windows:
+
+```typescript
+new AltairConfig({
+  initialSettings: {
+    maxWindows: 75  // Custom limit
+  }
+})
+```
+
+Or use persisted settings:
+
+```typescript
+new AltairConfig({
+  persistedSettings: {
+    maxWindows: 100  // This will override user settings
+  }
+})
+```
+
+## Default Values
+
+- **Electron**: 50 windows (unchanged)
+- **Web**: 15 windows (unchanged)
+
+These defaults remain in `packages/altair-core/src/config/index.ts` and are applied automatically if the user doesn't specify a custom value.
+
+## Validation
+
+The feature currently doesn't include explicit validation for the `maxWindows` value. Users should:
+
+- Use reasonable positive integers (e.g., 1-200)
+- Consider their system's memory and performance capabilities
+- Avoid setting the value too low (minimum 1 is recommended)
+
+Future enhancements could include:
+- Min/max validation in the settings UI
+- Performance warnings for very high values
+- Automatic adjustment based on system resources
+
+## Benefits
+
+1. **Flexibility**: Power users can increase limits for complex workflows
+2. **Performance**: Users with limited resources can decrease limits
+3. **Customization**: Different environments can have different optimal limits
+4. **Future-proof**: Easy to adjust as hardware capabilities improve
+
+## Backward Compatibility
+
+This change is fully backward compatible:
+
+- Existing installations will use the default values
+- No breaking changes to the API
+- Settings files without `maxWindows` will work as before
+- The feature is opt-in through settings
+
+## Next Steps
+
+To fully enable this feature in the UI:
+
+1. Run `pnpm bootstrap` to build the TypeScript packages
+2. Run `pnpm test` to ensure all tests pass
+3. Test the feature manually in both Electron and Web environments
+4. Consider adding a UI control in the settings dialog for easier configuration
+5. Add validation rules to prevent unreasonable values
+6. Update user documentation
