This is really cool. One killer feature that I don't know if you have considered is some kind of visualization of the stack trace, showing how control passes between the objects & functions. That would really help with dynamic languages, or large codebases that have been Greenspun-d heavily. It would be very difficult to implement, especially in a cross-platform way, but I bet if you pick a language community like c++, java or something else and focus on it, you might have better results.
