About ScratchTools
ScratchTools is a community-built Chrome and Firefox extension made for Scratch. It makes Scratching easier, through dozens of edits to the Scratch UI to make Scratch better than ever. Our group of developers, artists, brainstormers, beta testers, and press release managers all come from Scratch.
