Where can I go for suggestions related to Apple?

You can send feedback to Apple here:

Product Feedback - Apple

You won't get a response from your feedback, but it will be read. Also note that Apple had to implement an Unsolicited Idea Submission Policy. Unfortunately this was needed because people would attempt to sue Apple claiming that an added feature was actually their idea.

Legal - Unsolicited Idea Submission Policy - Apple

You don’t. Apple does not accept unsolicited ideas for legal reasons. You can leave feedback through the proper channels.
