https://alex-bates.com/scratchext/ ScratchExt adds cool blocks to your already huge Scratch arsenal and allows for awesomer stuff, including Mesh support (better cloud data). Disclaimer: ScratchExt is unofficial and therefore is technically not supported by Scratch. It uses some hacks to function and therefore there may be times when it doesn't work properly. ScratchExt does *not* use ScratchX because it does not have the sharing features of the main Scratch website. - GC
