I really like the whole idea of using blockchain for contracts, also the document creating process feels good to me. A lot of remarks and ideas are already provided by other commenters. From my side, the worst thing was that the e-mail notifiers immediately went to our SPAM-Folders. I think this is so damn important if your whole product is settled on notifying every party for a good process. Customization of the design of these mails is also something I would like to see.

BUG: I don't understand, why I always receive 2 OTP's with every login and I have to try out which one is the right one.
