Still waiting for that 2D matrix to eventually maybe be added. Even with lists, making a "grid" of values and referencing to them by XY coordinates is a pain.

Thanks for the help!

So basically, this new node could also be helpful for making a list such as an inventory?

Yes this would be a good example for a Map as you basically reference one thing with another so you can say you have 5 Apples and using the Map it keeps them connected.

I like this variable a lot. Thanks.
