Being able to generate the safe master password
Currently when creating a safe with a password as decryption choice, the user needs to invent a password, which will probably be very weak, making a password manager not very useful with such password. The shield icon that generates a password could be then placed just on the left of the right arrow, so that the user can generate a good one, and learn/copy it with an eye button. It may be also useful to give the user some insights on how to rememeber the password, etc.
