Would need a whole bunch more features for me to want to switch from pass (passwordstore.org), which has already great git integration, command completion, stores arbitrary contents (not just username, password and url), a whole bunch of extensions and clients (I need an iOS client), can generate passwords, and more.

Also I think the 6 seconds for pasting the password before the clipboard is cleared is a bit too short, pass has 45 seconds which is a bit too much, maybe something between 15-30 seconds would be optimal, or better yet: Let the user configure it.
