Organization of items via sales
Client want's to request a feature where in the register application inside of each category the items are organized by how much item is sold. Example: Item A has been sold a total of 22 times, Item B has been sold a total of 16 times, Item C has been sold a total of 20 times, Item D has been sold a total 7 times.
This way the order would be as follows of the items inside of each category inside of register: A,C.B & D or 22,20,16 & 7.
They also want to be able to change and add the colors inside of register.
