Hello, I'd suggest an option that becomes a button to "delete unused variables".
It is true that we should have control over what is declared and what is not used but when a project is big, it is possible that some variables are declared and for some reason disused and forgotten.
Ok, thats is my suggestion, only a button to "erase unused variables", globales, of objects and any variable unused.
Of course they are to Construct 3.
