Yes, Overleaf is awesome. I feel bad but I stopped paying for the Premium version with git-to-Dropbox syncing because the "stock" version is already so good. We put up a paper on biorXiv recently with Overleaf and two days later sent it off to a journal with minor reformatting. I only use Word for clinical collaborators these days, Overleaf is so, so good.
I still wish you'd support Markdown so that I could ditch Word completely. I hate that fucking program so much. I'd pay for Premium again just to use Markdown. :-)
I saw the D&D template earlier. That was hysterical.
I had not seen the markdown Beamer proof-of-concept. Very cool. Overleaf is the single best thing that has ever happened to my collaborative authorship skills, partly because Google Docs doesn't have a decent equation editor ;-)
