I know how you can add a sprite and some code to make a thumbnail that reappears when you stop the project, but it won't always show up as the project thumbnail in search pages, etc. So, there should be a way to add a custom thumbnail that is set as the icon for projects when you search them up or find them.

The project basically “screenshots” the current stage when saving, and makes that the project thumbnail.
You can save even without changes by pressing CTRL + S (CMD + S if you're using a Mac)

I don't remember whether it's instantanous or not, but if it isn't, you probably won't have to wait too long anyway.
