I have sublime text 3, but after I installed sublimelinter-html-tidy through the 'Package Control: Install Package', nothing changed. I also have Emmit, Bracket Highlighter, Side Bar, and a few others installed on my Sublime 3, and they all do what they are meant to do. They work. Only sublimelinter-html-tidy doesn't do anything, even though it is in my instaled packages.
Any help, or if someone could point me in the right direction, would be great.
