Hi! I've seen a lot of projects that have thumbnails that change, even though you haven't clicked on it yet.

Like this project here: https://scratch.mit.edu/projects/970915501/

Any idea how to do that?

pretty simple
draw your thumbnail on a sprite then add this code

when green flag clicked
set [ghost v] effect to (100)

all effects are cleared when you stop the project so it'll show up every time you stop and disappear when you play

thumbnails are made by what's on screen last time you saved the project, so you have to make sure you click the stop sign and it's on screen when you save

All of these thumbnails are typically made with extensions. I cannot name nor link any extensions but hopefully this helps. Pretty much you just use the extension to set the project thumbnail to a .GIF file (which is animated) that is separate from the actual contents of the project.
