Sounds like you've found a great solution.
Suggestion: You might want to move the parts of this message that are your detailed observations and suggestions about Rule Machine Manager to the Rule Machine release thread so the conversation w/@joshlobe can continue there in that context, other users might chime in, and the useful content is then easily found/tracked in the app release thread.
Glad you found/like Rule Machine Manager, I also believe it is a very cool app.
