Multiple revisions and author/editor revisioning

I've been playing with this module for the past few days... it's really nice, but I was hoping for something that had an easier workflow. I'm not sure this should all be done within this module, but in my attempts to get workflow and actions module working in conjunction with this, it just became very user UNfriendly. That said, I'm looking for more collaborative functionality between an author and editor.

As it works now, lets say we have User1 and Staff1. When a specific node type is created, it must be approved by Staff1 and then published. Now, User1 can edit this, and once he does it goes into moderation. Staff1 decides to edit User1's revision, which then creates a second revision. Now BOTH revisions are in the moderation queue, waiting to be Edited, Published, or Deleted. Add even MORE states of going back and forth between User1 and Staff1 editing, if User1 attempts to edit Staff1's revision, it defaults back to User1's revision.

Instead, I'd rather see something like: User1 edits node, it goes into moderation. Staff1 logs on and sees pending revision, edits it, and that creates a new revision, removing all other revisions from "pending" status. User1 can edit the new revision, and so on, until Staff1 finally Publishes. I haven't looked too deeply into the code, so I'm not sure if this is even possible since it uses core revision behavior...

Feedback appreciated.
