Just got around to using learnr + gradethis for a randomization experiment.
If i'm reading this correctly,
It seems this PR will fix the issue I'm having with my local .Rmd document (not as a package) and on shinyapps.io where my previous attempts are being cached, and I either need to manually "Start Over" or run things in a private/incognito window. 👍

Will this let me also put in the yaml header so that it never caches the previous attempts? Something like:

output: 
  learnr::tutorial:
    progressive: true
    allow_skip: false
    clean: true # <--- this option?
