I've seen streamers with commands where users can create, append and remove items from a to do list only for themselves. Eg, when each user adds or removes items from a list, they're only doing it to their own list, and cannot interfere with any other users list. I'm aware of ehsankia’s quote system, however, from my understanding this lacks the ability to give each user the ability to manage their own list. I know it is possible because I have seen it, but I'm unsure of how to do it. Any insight appreciated, thank you so much!
