Not being a grammar Nazi, but just pointing out a minor error to help with your English: if the sentence ends in "like", then you should use "what":

Can someone post a screenshot of what it looks like?

I'm not GP but thanks for the tip!

As a non-native speaker, I'd love if I were corrected all the time! These little mistakes are prone to getting stuck in your head and hard to get rid of if uncorrected (especially since the Internet is filled with non-native speakers making the same mistakes over and over again).

Curiously enough, I hesitate doing so myself when I notice a mistake, in case I bother or embarrass the guy. I think I'll start changing that :P

Looks like vim, it's just a vim buffer with the contents of the google doc. Not sure how it handles things like tables/images though.
