Not automatically, as far as I know. I made a ChoiceScript extension for Visual Studio Code, a text editor, that will show you every place you’ve used a variable. If you load your game in Visual Studio with the extension, right-click a variable and select “Find All References” (or press Alt+Shift+F12 when your cursor in on the variable). The reference list will pop up on the left. If there’s only one entry, for when you created the variable, then you haven’t used it anywhere else.
