Being a computer programmer who utilizes OOP (Object Oriented Programming) would like to do similar thing with TheBrains, i.e. have one Brain that can inherit (embed) child brains into it.
Benefits of this you can have separate brains for different types of ideas that you can use either independently or as part of the bigger brain with massive structure.
Then you can easy share the child brains or develop independently of parent brain.
I have modern computer, however brain PLEX lags quite a lot and more nodes i add creates more lag, sometimes i need to quickly brainstorm and put ideas in certain brain i don't want to wait or navigate trough entire maze of thoughts i can just open that particular brain and add thoughts directly its much faster then load parent brain and see them being reflected there.
P.S. You can store information about connections and links between child brains that combined inside parent brain within parent brain.
