i have the map list on the side. if you really want me to, i can make it so there is a tile atlas on the background, so you don't have to go inside the project or for just easier access. a great way to use this is to make a basic sketch of a new level, the S is for the start and the computer chip is for the save areas.
i made this the way it is (through stamping and my blocks) to make it easier to use in your projects, which is good because you used to have to directly edit a sprite costume, and you had to do that for every little adjustment. GAME CREATOR'S NOTE: this is better than a detailed map because it makes everything easier to understand where everything is.
