I agree—PonyDebugger is great. I think it's less trivial to use, though. My goal with the Spark Inspector (and it's setup assistant, which makes all of the project changes for you) is to bring down the difficulty and provide an experience on par with Apple's built-in developer tools. I'd love to integrate FScript into the app so you can issue SuperDB-style commands. I think I'm gonna try to auto-convert into their NextStep syntax so people don't have to worry about it, though - we'll see how it goes :-)
