The docs on their format were very useful, although the 1PasswordAnywhere was more useful when actually writing this. I also wish they'd switch over to their new file format everywhere, it's confusing to read all about the 1Password 4/5 file formats, and realize they aren't the one that's actually in use.

I also wish they documented the structure of their data after its decrypted. There are at least 3 different ways the data gets represented.
