It could go either way, no? I've also heard a lot of people complaining that debugging Racket programs is difficult because the stack trace is not useful, and this is because they use the command-line version which doesn't have errortrace enabled (by default).
Perhaps what you really are complaining is that the option to enable/disable errortrace is not easily discoverable. Would it help if at: [image: Screen Shot 2020-04-25 at 05.11.29.png] the text is changed from `racket, with debugging` to `racket, with debugging (slower)`. And the texts are linkified so that when `racket` is clicked, it leads you to the non-detailed language setting, and when `with debugging (slower)` is clicked, it leads you to the detailed language setting?
