The Live Tiles on Windows 10 for phones will be highly configurable if a latest leaked image is any indication.
A WindowsMania forums user has posted an image showing off the various types of background options that might be present in the next build of Windows 10 for phones. As we can see below, the user will be able to choose from opaque, semi-transparent and fully transparent backgrounds for the Live Tiles.
In case of an opaque background, a chosen image will be applied to the Live Tiles instead of the underlying portion of the homescreen. The transparent background option will give a suitable color to the Tiles and the image won"t be applied to them. Without seeing the actual options, it cannot be determined whether the level of transparency is configurable or preset but this image gives us a fair idea of what to expect.
A set of images from a recent Windows 10 build for phones had leaked recently but since this feature was not mentioned in any of those, we believe these images may be from a newer build which means we can likely expect some more leaks in the very near future.
