Better functionality added to Requirements

The Requirements have been extremely useful, 
I would love to see the following features added. 
1. The ability to search by ID when selecting the Link to requirement from a test case. 
2. The ability to search by ID Name in the Requirements window. 
3. The Ability to group Requirements, ie   Feature ABC  may have 20 requirements, I would like to group all of those together, and have reports based on features. 
4. The ability to view the status Pass/Fail of test cases assigned to a requirement, it would be great top have a requirements tab that works in a way like the coverage tab to show coverage by requirement, and status of linked tests. 
5. The ability to set requirements to individual Test Steps not just Test Cases.
