If you are into visualizations, you also might find my debug visualizer extension for vscode helpful:

When debugging JS, there is a nice way to provide visualizations for application specific objects without touching the application code.

Combined with time travel debugging which allows to step backwards, it is really easy to understand complex algorithms:

The visualization library is independent and open source. There is also a rust cli and a web playground. I'm very open for contributions! (especially new visualizations)



Looks quite nice.

Maybe you already know this as background work for your plugins, but Symantec C++ was one of the first IDEs to provide this kind of tooling.

I had quite some envy not having similar feature on Borland compilers.
