StellarGuard
Well, obviously it doesn't feet into support wallets. There's a little sentence at the end about integrating StellarGuard into wallets, so maybe the mention that cosmic-lib comes with transparent StellarGuard support could go there.
I think that ideally you could have a page dedicated to StellarGuard integration with some precise instruction and relevant links that is listed in the footer, on which you could dedicate a few sentences to cosmic-lib. As a developer I would expect to find that kind of information easily, without having to mail the author.
(Edit: by the way thank you for adding Stellar Authenticator)
