Now I have Polgar's Mates. Add some other PGNs, like Anatoly Lein's Sharpen Your Tactics, Susan Polgar's Tactics for Champions, or maybe even some more advanced puzzle sets like The Woodpecker Method and Perfect Your Chess.
This will necessitate a change to the data structure used in Firebase. The documents will have to have different fields for each data set, and nested in those fields will be the states of the individual puzzles. Also necessary will be a drop-down menu to choose between the different puzzle sets and a variable for each user storing which puzzle set they are currently working on.
