• [✔️ ] Docs have been added or updated

Other Comments I've updated lg-gutter so that it shares same functionality as new lost-vars method, save duplicating code. Only thing I'm not sure you'll like is how I've broken out each of the new variable methods into its own file. See what you think, I can always change it if you aren't keen.

At this point, since it's done I don't see why it has to wait for 8.3. I'm the holdup on 8.2 and getting the test coverage up #381. 😳
