 * **Responsive behavior** - the map will automatically adjust (pan & zoom) if the user changes the window size or orientation (on mobile devices). [The problem's description](https://yootheme.com/component/answers/question/52808).
 * **Custom pin images** - you can set a custom icon for all pin markers or set a unique image for each marker ([Read more](https://github.com/rvalitov/widgetkit-map-ex/wiki/Customizing-marker's-pin-image)).
+* **Google Maps API key** - you can enter your key that will be used in all instances of the widget. [Read more](https://github.com/rvalitov/widgetkit-map-ex/wiki/Enter-Google-Maps-API-Key)
 * **Advanced markers clustering mode with custom images** - a full control of grouping the markers into clusters to provide a better user experience. Online collection of markers is also available. [Read more](https://github.com/rvalitov/widgetkit-map-ex/wiki/Markers-Clustering).
 * **Center map** - you can put an arbitrary center of the map. This feature is not available in the original Map widget - problem exists since 2013, e.g. [post#1](https://yootheme.com/component/answers/question/75957), [post#2](https://yootheme.com/component/answers/question/52808).
 * **Correct visualization inside the lightbox (modal)** - there's a problem with the original [Map widget](http://yootheme.com/demo/widgetkit/joomla/index.php/home/map) when the widget is not rendered correctly when displayed inside the modal dialog: the map tiles are not rendered completely or partly, so the widget is not visible properly. This MapEx widget fixes this issue. [Read more](https://github.com/rvalitov/widgetkit-map-ex/wiki/How-to-show-map-in-lightbox).
 * **Correct visualization inside other widgets** - widgets from Yootheme don't support nesting inside of each other. This MapEx widget fixes this issue and can be used inside other widgets (e.g. Switcher) or UIKit components (e.g. Tabs). [Read more](https://github.com/rvalitov/widgetkit-map-ex/wiki/Display-MapEx-inside-other-widgets-and-UIKit-components).
+* **Auto close (hide) popup windows** - you can set an option to automatically close popup info windows, so that only one window can be visible at at time.
 * **Tooltips for all options** - it's much easier to use the widget, because tooltips are available for all settings.
 * **More map types (Roadmap, Satellite, Hybrid, Terrain, Styled)** - the widget supports all standard map types that are available at Google Maps, [read more](https://github.com/rvalitov/widgetkit-map-ex/wiki/Map-types).
 * **Advanced map controls** - you can customize visibility of all map controls and tweak their look, [read more](https://github.com/rvalitov/widgetkit-map-ex/wiki/Map-controls).
 * **Sophisticated styling options** - you can create your own custom map with unique appearance using various styling options and Wizard, [read more](https://github.com/rvalitov/widgetkit-map-ex/wiki/Map-styling).
 * **Support of SEF URLs** - search engine friendly links are supported, no matter where you publish these links in the widget, [read more](https://github.com/rvalitov/widgetkit-map-ex/wiki/Support-of-SEF-URLs).
 * **Update notifications** - you will be notified if new versions of the widget are available.
+* **Multilingual interface**, translated into languages:
+	* **English** (en_GB)
+	* **Русский** (ru_RU)
+	* **Deutsch** (de_DE)
+	* Your language not listed? You can help with translation, [read more](https://github.com/rvalitov/widgetkit-map-ex/wiki/Translation-issues).
 * **Access to the original [Google Map object](https://developers.google.com/maps/documentation/javascript/reference#Map)** - Javascript object that is used in creation of the map. So, the user may change and/or modify the object as he needs from any web page using Javascript which provides vast opportunities for Javascript programmers to customize the map using native [Google Map API](https://developers.google.com/maps/documentation/javascript/tutorial), [read more](https://github.com/rvalitov/widgetkit-map-ex/wiki/Working-with-Google-Map-object-(for-Javascript-programmers)).
