Great tools for Scratch! Lots of useful extensions like Opacity sliders and others, and more tools for convenience like Onion skinning! A must get for Scratchers overall.

Epic extension! Not only helps a lot with creating projects or using the forums, but the community around the extension is also extremely nice.
EDIT: I regret being hesitant for around 3 months about using it or not as well.

Great stuff.

This extension must be used by every Scratch developer. It makes the Scratch experience much better!
