This is a simple demo where you can add/delete things from a list; and check whether certain things are in the list. The item number variable is what item the thing you checked for is on the list. Feel free to copy the checker code, just give me credit! (You copying the checker code is kinda the point of this project.)
I realized a few minutes after I made this that it is literally built in with the item # of ( ) in list [ ] block. Oops! All the work for nothing. Still, it was fun to create.
