Frame market theme disappointing

I can't understand why this theme is advertised as an ecommerce theme. there's nothing especially ecommercing about it.
Plus the theme choices are lacking some options as far as I can see.
The background covers the entire board without any segregation for the text area.
The nav background and buttons are not customizable.
The custom header image crop annoyingly small than the given crop markings, by about 20px all round.
Feel like I have wasted my time trying to get it how I had hoped. Quite a disappointment. Sorry!
