Things I noted:
- Each entry gets its own passphrase. You could use the same one again or again, or change it up. The addition of a 'hint' is nice.
- The title default should clear when you enter it with your tab or mouse focus. That's a minor thing, but annoying.
Regarding the keys used in the browser, is it possible to have whatever key phrase we enter also be seeded? That way, if by some miracle your database was compromised, anyone that did happen to use the same key passphrase over and over would have an extra level of protection? (Crypto people out there, does this actually give any additional protection, or am I just piling on unnecessary steps?)
