Post about the little things (excluding highly published features) that have changed in iOS 15 here. Note that this is a wiki post, which means that you can add directly to this post.
NOTE: As always this is NOT a thread for bugs, questions, or troubleshooting the betas. All posts must present a new feature or function, or new behaviour not mentioned in the keynote. Please screenshot where necessary. Comments on features are welcome, but stay on topic. This is also not a thread for whining about missing features, complaining, in-fighting, or personal agendas. Keep this informative and to the topic at hand.
