Most of us are using multiple devices nowadays: for example a work computer (Linux), smartphone and tablet (Android, iOS, Windows) and a home PC (Windows, Mac). This tool would be much more useful if you developed versions for other platforms with the ability to synchronize the password database between them.
Note: when I say synchronize, I don't mean cloud storage. I mean the ability for the different versions to communicate changes via a local network (home WiFi) or the database on a USB key or memory card.
