Adding Extra Features to Products

Hi,
My store product is Books.
ISBN, Bar Code and Author are some specifications required for the Books.
I added these 3 columns to Product table as nText.

Thanks to Nop-Commerce Team who helped me in making these 3 new columns Searchable for viewers.

Now the issue I am facing 2 issues

1. How to display them?

2. How to add them to Product Management at Administration Section for adding new products or editing the Products.

---------------------------
I can anyone help me in this please? I am really stuck :(

Any clue how to solve this issue ?

Since Nop Commerce Team dont wish to provide support in this matter .... that brings me to one final question.

IS IT POSSIBLE TO ADD FIELDS IN PRODUCT TABLE AND ABLE TO DISPLAY AND EDIT THEM ALSO ?


If the answer is NO:
I would simply search for other e.commerce solutions


If the answer is YES:
I need guidance to complete my store then BUY the Nop Commerce License and Launch my site
