> 1. Allow me to step through the code execution paths that have been modified in the pull request, based on the tests that have been modified.

Not sure if I fully grasp this! We tried to kind of do this in previous iterations (show call graphs all at once) and it gets messy very fast. Could you elaborate on this point in particular?

Sure - imagine my PR adds one new test which test one new function.

Starting from the test, allow me to step through the program execution, just like a debugger, to observe variables, surrounding code, and the complete file.

If you read only the covered lines of code in a linear way, you'd miss the refactoring opportunities because you aren't looking at the rest of the file.
