You can send feedback:Well that's a disappointment. Not too often that Apple disappoints me, but this is one. That was a handy feature. I won't bore you with the details, but I have some situations where it was nice to be able to be able to tell at a glance if my Jabra speakerphone was connected. Does Apple have a system in place to ask for features to be added or reinstated?

In most cases, Apple won’t reply, but they’ll certainly read your feedback.
