Let's start with the backgrounds, which will be available in a re-organized panel in which the images separated by category (Classic Stripes, Earth & Moon, Flowers) are collected. Note the rumors "Home Screen Appearance" is "Smart Gradient", which will allow you to view the dynamic wallpaper only on the home screen. There are four options for each color.
The other news would have sensational: 9to5Mac in fact, it would have found traces in the code of the new operating system of the so-called "Avocado" function (this is the company's internal name). In practice, it would be aapp for managing the home screen.
Translated: Apple is working for bring widgets directly to the home screen both iPhone and iPad. Unlike those we already know for the tablet – fixed – and for the smartphone – with a dedicated screen accessible via a swipe on the right – the "real" widgets in development will have the same behavior as those we already know well on Android. In practice, they can be freely moved and positioned where we believe best.
Be careful, though: this is a function still being tested, and (a) it is not said that it will be introduced in iOS 14 and (b) it is not said that it cannot be rejected. For now we report only the fact. Would you like to have widgets on your iPhone's home screen?
