Hinting for code ability


Hi! I know that Glitch uses CoreMirror for a code editor. I’ve looked to the CM site and found an addon called hint/show-hint (that is actually a block “hint” that has hinting for JS, HTML, etc.).
So, if there is an addon that would turn Glitch’s editor to a professional, as others editors is, why there is no hinting?
