The “USB-stick” page shows the SVG images on an USB stick/drive when it is inserted into the MDA.
At the top of the page you’ll see the last image that was sketched by the MDA. If you click on this image the MDA will start sketching the image again.
Below this the images on the inserted USB device are shown. By clicking on an image the selected image will be sketched.
If no USB stick is present, or when there are no SVG images on the USB device, a message notifying you of this will be shown instead.
