I just found out tvOS 12 will tell you where a screensaver is located (tap the remote’s touch surface), and allows you to change screensavers by swiping left or right on the remote’s touch surface. Pretty cool.
Yup they demoed this in the keynote. It makes a lot of sense. In fact my parents asked the day before the upgrade about where the aerial view was they were looking at and I told them, “ask me again tomorrow”
