I made a video of me using our debugger to compare two recordings - one where the program worked and one where a very intermittent bug occurred. This was in code I was completely unfamiliar with so would have been hard for me to figure out without this. The video is pretty rubbish to be honest - I could never work in sales - but if you skip the first few minutes it might give you a flavour of what you can do. (I basically started at the end - where it failed - and worked backwards comparing the good and bad recordings) https://www.youtube.com/watch?v=GyKrDvQ2DdI

Also a bit about using it to record Kotlin, set bookmarks in the recording, jump to timestamps and so on.
