pretty damn fantastic, from a user-friendly standpoint almost perfect, security wise it's also OK, though i'd wish to have a few thingys to make it really perfect:

- more PBKDF2 rounds, lots more.

- option for a "Secret key" implementation like Onepassword, or a "key file" like keepass.
this will prevent you from being at the mercy of password guessing attacks if the data ever gets stolen/leaked.

- password history, definitely the main thing missing.

- desktop version, but you alreaddy know that/are working on it ;)

thanks for providing this awesome password manager as open source software.
