I made this project to demonstrate a way of making lists bigger. Usually you will have trouble saving a project with a list much bigger than 250000 items (with an average length of around 5 characters). This list has 999999 items. I did it by sharing it from the Scratch 2.0 offline editor. The main problem is that you cannot edit the project after you have added it.
I thought of the method myself. The list was generated by a small python project that I wrote and imported into scratch. So this project is: 100% Me!
