How about adding "Tables 1-10" and "Tables 1-30" to the categories? And maybe add two sub-categories: With Friction and Frictionless?

Very good idea, I will add a few additional categories

How about adding me as a mod as well? It can get really tiring having to verify all the runs by yourself.

Plus, I can help you organize the categories so it's better to read.

FYI: You don't add sub-categories like that :)
