Variables are cool, but only in programming, not UIs. I suggest showing the variables as sentences instead.

If you don't want to create strings for all of them, you could attempt to parse them as sentence case (foreach until you find a capital letter, add space before, capitalize the first word...)

I assume you mean the naming of the config options? This has already been changed in the development code, all the config names and comments now have localization strings, and the default names will be upper/camel case with spaces.

See this comment for example screenshots: #93 (comment)
