I'm currently on vacation, but I noticed an MP-II alpha and its source were release, very exciting!
I too am hoping there's a solid basis this time around, perhaps some one or more of the core developers could give a quick design overview here? As DricuS said, no need for extensive UML diagrams, but just a basic overview of the architecture?
I look forward to checking this out when I get back, and hope to be looking forward to writing my own plugin soon
