Meta Nodes are great, but it would be even more amazing if they acted more like "Functions" or "Objects"...
For example, I just made a really interesting little pattern that slices and dices data a certain way then puts it back together.. I'm going to have two different (but similar) inputs go into this pattern.
As life has it, things might change. Wouldn't it be great to be able to edit one meta node, and the other one changes as well? (in fact, the other "Clone" is just a reference to the original meta node)
