>I use Beautify on inherited code that has no rhyme or reason to capitalization on indentation.

I use it on my own code every few minutes. This allows me to just look at the code and see if there's a closing of a block that's on a wrong tab (so there's a misplaced something, or a missing something). Also, I camelcase my variables the first time I use them, then later I don't - type them all lowercase, or camelcase, and then when it's beautified they get cased as in the first instance. Now if the capitalization is not what I expected - then I probably used the same var somewhere above, hmm, look it up and see what's wrong. If a variable remains lowercase, I have a typo, check that.

And I don't have to indent a bunch of lines if I decide that they need to be wrapped in an if/end or other block. Beautifier does that much better and faster than I do.
