I am the author of Passpie and one of my goals with passpie was that it should be as configurable as possible. Pass(http://www.passwordstore.org) is a great and mature cli application and as with any great applications there are alternatives.

History (undo/redo) is planned on passpie, probably using git as well.

Some ideas are: passpie history --list passpie history --undo XYZ passpie history --redo ABC passpie history --backend git --redo 123 passpie history --sync

You may like pass you may like passpie you may like both. :)
