can make up to 10 cloud variables, therefore can make 10 cloud lists... COMPATIBLE WITH SCRATCH 3.0!!! Also, if you want to use this in your project, look at the documentation in the sprite. This, as far as I'm concerned, can store about 1260 (for all ten lists) characters in the cloud. With encryption, It might be able to store more.
I worked on this for 3 weeks... and this is my biggest project so far! It uses Translate to check connection to the scratch servers, as the request has to go through the scratch servers before it can go to Google.
