I use this tooltip more often lately. I guess this can be extended with information on where it's being used / what it's dependencies are. And use syntax highlighting to differentiate between scoped vars, global vars and system vars?

The feature looks bit different than what is original shown there, but we're working on a way to visualize how apps are connected under the hood / make it easier for you to follow connections through your app.
