Just a couple of features:
Store to support more than one product type, ie iphone 4, iphone 5 and Samsung S3, ipad, ipad mini and so on.
To be able to have custom masks like what [url removed, login to view] is but for different products, that will have their own case picture and different value between the dotted line and cover picture. Still based on the same kind of system as the photoshop template I sent you. So might need a simple way for me to enter values or a guide on how to do it.
Not sure if this is easy the ability to scale an image none proportionally if a user desired to do it that way. Maybe a toggle on/off feature
To have pre made covers on the site.
