Nice work: very fast and seems stable. The buttons are a little unintuitive: "Info" shows all of the database tables in a useful sidebar, which can be clicked to show their contents. This button should be called "Tables" and live in the top of the app. The "run" button, although it is at the bottom of the screen, actually refers to the entry at the very top: it should be put there. Read the Apple HID guidelines, and this will be a great little utility.
