Hello Playmaker!
I have a tiny suggestion that's not revolutionary, but it can be helpful. Variable Browser
Simply this: You can use it to look at all Variables in the project. And you can see what the variables are doing while in Play Mode. It can be filtered to a GameObject or only a specific FSM.
This can be useful for debugging. For example: If a variable has a wrong value, you can figure what it is, and deal with it immediately without having to go to the FSM then the variable.
