Hi,

     WenDong, I think your proposal is cool. However I believe there's some
place to enrich. Mainly, what basic algorithms are you going to use to
generate the minimum closure from the CLOSURE by the nodes? And how are you
going to resolve the problems that you raise?  And what is your design of
the user interface and "other changes", etc?

    I believe a detailed proposal can help everyone to understand your plan
and design. :)
