A better pen save system. Press "S" to get save code, press "L" to load a save code. Use the "Track" block to start drawing. Use the "Save" block to save the current drawing to the "Pen Data" variable. Use the "Load [code]" block to load pen data and draw it to the screen. Use the "Clear" block to clear the current drawing along with it's data. When using the "Track" custom block to draw, changing the "_penColor" variable will change AND save the pen color. Same goes for "_penSize" :)
