Lots of reasons to love a visual debugger: - Easily set breakpoints and localize faults quickly. - Enter the debug shell and evaluate statements based on the current program context. - Tinker with variables at runtime and see how the code responds. - Conditionally catch things that are going wrong and evaluate program state at the time. - Simulate difficult-to-reproduce things like race conditions by messing with program state. - Use it like a CLI to do stuff from the program, like send requests using the actual program code.
