Add unused variable highlighting #155

Closed grkek closed 1 year ago

grkek commented 1 year ago

I think having a highlighting feature for unused variables would be a great addition for better user experience

Thank you for your contribution! It appears you have a regex \\b_([\\w]+[?!]?) for matching unused variables, would \\b_\\w* work or is there an edge case I'm missing?
