At my job, we do Java, and it would be wonderful to have something like this. I litter System.err.println around the code then run it so I can better understand the behavior, so the idea of doing the equivalent in a recording would be awesome! I don't know how my colleagues manage with a regular debugger, it's like looking through a pinhole, you only see a tiny part of reality.

Try to use the debugger, learn breakpoints and watches. Unsure what IDE you use, but if you use Intellij, this will get you started very quickly. https://www.youtube.com/watch?v=lAWnIP1S6UA

Very interesting. I can change a breakpoint to not break, but log, instead. This should be quite interesting. Also the option to "go back in time" by dropping a frame from the callstack is very useful. This way, it's possible to go over some part of the execution again without having to restart the whole application.
