[feature request] Allow Preview in plain text

[injeniero]

We are generating Markdown, but we would also see the plain text version to corroborate the spaces and detailed format is correct.

HA! Turns out it is in there but we've been terrible at documenting:

I'm using that feature already and it is great, my request is to be able to see the plain version(exactly what is going to be send in the request body) so I can spot extra spaces, bad indentation, etc. Just like many playgrounds do.

@sethjuarez I can't reopen, so mentioning you to get your attention.

OH - I understand then.
