This is how you made a thumbnail on Scratch! Press the left arrow key or click the left button to go to the previous slide! And click the right arrow key or click the right button to go to the next slide! There's Scratch Addons link on the top of the screen or in the thumbnail! You can download it to use Scratch easier! :D
Update: I fixed the bug that make the next slide repeats that do not wait! Added in 27th of August, 2023. Thanks @Lucasphoang2021 for helping me how to fix the bug! Wait until mouse down? (Mobile) Right or left arrow (Computers).
