I managed to install Package Control and install JsFormat through it. The command, "Package Control: List Packages" shows that JsFormat has been installed. Unfortunately, neither the key binding nor typing in the command into Command Palette work. It seems as though the package is installed, but bears no effect.
update: everything has worked out and I have no idea why. I've been messing around with mapping files and perhaps some internal cache got cleared. Anyways, thank you if you've spent the time to follow my chat.
