Default passphrase length in Generator

Currently the password generator uses the last password length selected. Generally I change the passphrase length to shorter because a site has a lower limit. I don’t want to use shorter passphrases in any other circumstances, but I also don’t want to have to always audit the passphrase length and use the horrible slider UI to select a length.

Allow me to set a default length to always use and make the override UI a text box I can be precise in.
