ok 2 things today.
The first is by Alex Chouls. I hope I'm not overstepping it here if I take the liberty of quoting your content here, Alex.
You can quickly deselect a variable by pressing Esc. It's very useful if you're having a lot of different Variables in one FSM and can't find an empty space to click to deselect the variable.

If you directly change a prefab, those changes will remain even if you stop playing the game. So if you need to change a certain parameter on a lot of gameObjects at once, you could create a (nested) prefab and add every gameObject that needs changing as a child of that prefab. Then you could create an FSM and go through all of the childs of that prefab and do certain actions. Like you may have a naming convention and you could string compare and then have a lot of different changes tailored to that type of GameObject. Then you can stop running the game and all the changes remain. You can then drag the different prefabs back onto their real prefab (if they have one) and voilá, you've then changed an indefinite amount of different objects permanently and all at once.
And yes... I do need to redo the last few tips, they are too hard even on my head, even though I wrote them myself
