Perhaps to keep elements to a minimum, either "grey" out used elements that are no longer needed for later game-play, or a put a number next to the element to show how many more times its needed for use....this will eliminate pointless clicking and the creation of elements that you already have..
 "Doodle God 2"){kind=icon}
 "Music Catch 2"){kind=icon}
 "A Small Favor"){kind=icon}
