Search up "scratch addons" on your search (google) Its an app, and it directly goes to your scratch account simply by downloading it then refreshing your Scratch tab. It should give you a Pause button and a Search in editor feature. To turn on other addons, go to the Scratch Addons website again and click the word "Addons" which is at the top right of the screen. Then, on the any addon, click the little gear shape, which is under the picture of the addon but above the text. Then it should bring you to a dark screen that still says Scratch Addons and you'll see a search bar, where you can search for Addons you want. Once you find an Addon, turn it on by clicking the little switch icon(it looks like the Bluetooth switch but orange.) Personally, these are my favorites (see below) - Onion Skin for animating -Opacity ( only for vector and is a little glitchy) - Costume restore (like if you accidentally deleted a costume) but keep in mind that the restored costume will be at the bottom. That's it. Thank you if you read all of it!
