Capabilities/Requirements Editor?

Hi. I was wondering if there exists a bndtools-based (or just eclipse-based) Capabilities/Requirements editor UI?

I understand that there are annotations that add capabilities/requirements for lots of the osgi resources (packages, osgi services, etc) and that bnd can generate the manifest.

I’m looking for a UI that would allow new namespaces to be created, and Provide/Require manifest entries to then be created more easily…maybe with a tester/checker too?
