> "Is everyone really going to open a separate application, unlock the vault every time they want to use it (due to timeout), Ctrl+F for the URL, and then Ctrl+C out the username and password every time they want to visit a site? Also, is everyone going to create a correlated entry every time they make a new account?"

This is not how pass or KeePass work. I recommend you try them out and see if they're really that hard to use (hint: they're not).

If you really like browser integration, I also sometimes recommend using the built-in Chrome or Firefox password managers with good master passwords. They're actually easier to use than LastPass and its insecure ilk.
