There is no action that can take a blackboard variable object and expose it’s properties right now. I can probably take a look at this and create some reflection based action that does this.
Your idea of selecting BBParameters similar to dot notation is a nice one, but because this would take place with reflection it would be quite slow.
Regardless, I will take a look at your requests and see what’s possible and what’s not. Can’t promise anything though especialy for the 2nd one 🙂
