Whenever ScratchTools is adding new features, they get added to the beta version first. After the beta version has been tested sufficiently and it works well, the beta version is submitted to the extension web stores, and eventually are sent out to all the users. We want to make sure that there are no bugs present in the beta version, and no bugs will reach the users. To do that, we need the help of beta testers.
If you want to beta test, it just means that you need to use the beta version of ScratchTools. It's super simple to get set up, and you don't need any special devices or new apps. And, if you find bugs, you can get credit for what you find. If you're interested in helping out with beta testing, just click on the "Enroll" button up above!
