The FireUI Multi-Device Designer makes it easy to create user interfaces across multiple form factors, devices and target platforms using a single form file. The Multi-Device Preview provides a design time view of what your application is going to look like on a wide range of devices. This gives you a great visual aid for developing your applications, allowing you to easily identify which user interfaces you may want to fine-tune for a specific form factor or device.
The Multi-Device Preview window shows a preview of the current active form across all selected devices. Zoom in to see a detailed view of a specific device, or choose from different view modes to change the presentation of the devices in the Multi-Device Preview window.
