- Full analysis of dependencies’ consistency (build configurations,compiler flags, cmake options, etc)
- Detection of potential cycles (circular dependencies)

- Dependency Management for Simultaneous Multi-Project Development. Someone needs to refresh my memory about what this means
- Downstream notification system (when patches are applied upstream)
- Support Index overrides in package metadata
- Support search by identifiers (i.e. git sha, unique tags, symbolic names)
- License analyzer (i.e., please warn me about using GPL’ed code)
