Aarush Kalele (ID: 000000762d78eb9b) Voted 5 ★ - Updated 11/26/2023 This is the greatest scratch mod ever and I wish all of these ideas were in real scratch! My favorite features include the pause button, mouse position display, editor find bar, jump to block definition, convert variable to this sprite only, clone counter, running block border, and the debugger panel because these features make it so much easier to find and fix bugs in scratch games! Everyone who uses scratch a lot because not only does it make coding a lot easier, it also improves other aspects of scratch like adding customizable website themes, speeding up project loading times, being able to set a project thumbnail, and a lot more that I would list if it weren't for the fact that there's over 100 addons that you should find out for yourself. Making sprite costumes is also super easy with opacity sliders, skewing, edge snapping, and onion skinning. If it weren't for all that, there's also an option to enable cat blocks, which no scratcher should be without. Finally, the most useful feature is the built-in message notification system that lets you read and reply to comments from other scratchers through the extension pop-up without ever leaving the game you're working on! If you don't already, you should get this extension, because scratch just isn't the same without it,. Thank you griffpatch (and everyone else who made addons and fixed all the bugs)!

WildBlueScienceFanXD (ID: 00000019ea0af027) Voted 4 ★ - Updated 11/11/2023 Its good, but i honestly want a merging/cutting/dividing shapes addon. I dont wanna remake the borders of specific shapes just for something i wanna do.

Caven Bonsell (ID: 00000078d6f3b00d) Voted 1 ★ - Updated 11/04/2023 It stopped working after like a year. No addons show up and dark mode does not work. Scratch Addons is terrible. I contacted Scratch Addons and switched to a different Scratch customizor until this problem is fixed. Edit: Chrome keeps saying it may be corrupted. Is this Chrome or the extension's fault? It does not do it in Edge. Most likely it's Chrome. DAMN YOU CHROME!!! CONSPIRACY!!!!===
