It's a shame that it now requires an external application to function, I can't use it anymore.

Just discovered Buttercup. Wow! What a great password manager! I've tried most of the majors, but I think this one is a keeper. Apart from the fact that it is open-source, the feature I like most is that you can choose where you want to store your (encrypted) password archive file, and how you want to access it. Two thumbs up to the developers!
