I know this has been mentioned before, but I feel it worth mentioning again. It would be great to be able to completely reset progress on modules/paths. I had to take an extended hiatus, for example, but when I came back to refresh, all my answers still being there made it easy to gloss over and not cement the information again. It would be much more effective for learners who sometimes have to take time away to be able to reset a module and go through it as if new again, instead of having to create a new account (which is counterproductive to the amount of cubes I have). I would even be down if it cost a few cubes for each module you reset. Just my thoughts.
