It would be really great if I could add a column price on the ALL PRODUCTS page on backend.
Then I could see the price of a product without clicking on the product first. For example when I have 12 types of limonade, I can type 'limonade' in the search field, all the limodes are visible on the ALL PRODUCTS page and I can see what the prices are.
You could have a little custom app made to display a custom layout of products in your admin. It would be accessed through a different link to your normal product layout but would provide the ability to customise based on what you want to see.
