Bibleworks, I want you to know that you lost my trust with Bibleworks 7. It's going to take more than "New Features, New Databases, and New Version!" to win it back. It's going to take a whole new approach to usability and quality control.
Regarding usability, I have just this advice. Play with Accordance. Find out why people love it. Emulate. Keep your crazy command-line based interface for users who like it, but offer something easier and sweeter on top. Oh, and by the way, if I delete the logic operator at the beginning of the line, don't put up a modal dialog box asking me what I want to do. If you don't know why that's bad interface design, welcome to the 1990's.
Regarding quality control, I offer one exhibit. Open up any biblical text in Bibleworks—English, Greek, Hebrew, doesn't matter. Place the mouse cursor just to the left of a character. Click the mouse button. Drag the mouse to the right. In every other program in the universe, this will select that character and all the characters to the right. Not Bibleworks. An ancient, neglected bug causes this maneuver to skip the first character. Let me just be clear: Bibleworks has a bug in selecting text. Selecting text, for crying out loud.
Do I want to pay $149.99 for the privilege of experiencing more of this kind of agony? No thanks. I'm stuck with Bibleworks 7 because I can't afford to switch to another program. But I'm not throwing good money after bad.
