If you name a craft "_something" you won't be able to see that craft in the crafts list, but if you search something in the searchbar then it appears
EDIT: I'm regreting this bug report because now I see the possibilities of hiding the crafts, my list is too long. But I'm sure that the possibility of creating folders of crafts is a much better solution, so I'm going to keep it up
EDIT2: Points are also problematic, maybe the game shouldn't allow the names to have those characters
@Majakalona you just mansplained to a game dev
