Very slick. I see the value as a developer looking at my in memory data. Not sure on the best monetization route but nice work. A way to import JSON might be a nice feature where it could be used by non-developers to visualize data and navigating as well. Good luck with whatever path you take.
Thanks Attila! That's reassuring to hear—I've mostly gotten responses that it's unclear how it could be useful, though that may be largely due to my unclear communication. (That also relates to my older video, since I haven't shown this one to many people yet.)
As for monetizing, I'd like to sell it as a cheap utility for programmers or CS teachers (those would be two different products). If I can make enough to visit the dentist regularly and maybe just supplement with part-time grocery store work, I'll consider it a success. Of course I think it has the potential for more than that if properly executed on...
