I have been trialing the 1Password for Windows version. It's nice. I'd love to see more usability options and features, such as those found in Roboform and LastPass. One suggestion, it'd be nice to have a checkbox to visually see the password when changing the Master Password. Also, a password hint option would be great. I think a danger in not being able to see your Master Password change is...what if you enter the wrong password twice, and then change it, and can't get back into your vault. Need that checkbox to be able to double-check you're entering what you think you're entering.
