Apple has been granted a patent (number 10,140,742) for an “automated graphical user interface layout” that hints at changes that could come to its iTunes interface. It involves nothing major; the invention would match colors that are complementary to the interface items that you’re viewing on your device’s screen.
As the prevalence of electronic devices has increased, content, such as movies, music, images, etc., has largely become available in a digital format, displayable by electronic devices such as Macs, iPhones, iPads, Apple Watches, and Apple TVs. Digital content players for electronic devices have become very prevalent.
Apple says that, because of the popularity of these players, manufacturers of these content players naturally try to enhance the user experience. Still, content players generally have a static layout (e.g., static color-scheme, background images, etc.) that doesn’t change based upon content that the content player is displaying. Apple wants to change this.
Of course, the company files for — and is granted — lots of patents by the U.S. Patent & Trademark Office. Many are for inventions that never see the light of day. However, you never can tell which ones will materialize in a real product.
