I’ll +1 the request for a ‘local’ blackboard. I think it’d be nice to clean up some things.
I don’t know which way it’ll be implemented, but for me, a simple way would be to just have the ‘global’ agent blackboard at the top-right like now, then underneath it, and identical window, but for local blackboard variables that are only for the current graph. This way you have access to all variables, and it wouldn’t impact peoples existing blackboards.
