Here's how to use these: 1: Notice the tab on the bottom of your screen, labelled BACKPACK 2: Click that tab, and the BACKPACK will open 3: Locate the sprite you wish to save in the sprite list 4: Drag that sprite into your open BACKPACK 5: It may take a few seconds on slower hardware for the sprite to save in your BACKPACK 6: Do not drag a costume into the BACKPACK! It will not be saved
I just changed the thumbnail because it's lagging all the time.
