i have app where u can pick fashion accessories like designer purses and shoes and put on to a cork board. to make cool trend inspired boards. there are a bunch of these little fashion graphics that you can pick grpahics from a menu and put them on to cork board and move to make a cool collection. does anyone know of any key terms or tips for how i could tell which was the last graphic touch. so i can hide or "delete" it from the corkboard? any terms i can use to further figure this out or a tutorial would be great! thank you !
