Composer feature (as well as others) should be better documented

The ability to edit multiple files with AI seems huge. But the feature is hardly documented!

It’s not immediately obvious how to best use this. Some UI elements are confusing. If I @ mention something in the prompt, it doesn’t show up as included in the above “context” area. Why? How are these different? What are the best practices on using this feature?

The cursor team is doing amazing work. Would love to make sure that all the value of what ya’ll are doing is being fully realized (even if these things will change b/c it’s a beta feature)
