The ability to create pattern repeats is very useful when it comes time in designing your own apparel or home decor items such as pillows etc..
I have not found anything that has been missing from this program yet but if there was something i wish they would add maybe some more options of different sizes per unit? It does what its suppose too! This makes my job easier by allowing me be able design products quicker with less mistakes since everything can fit into one place so easy now days without having multiple programs open at once which used t o do before also saves alot of space!!
