When you quick edit a product, the option to edit the price is there. However, the only way to edit inventory is to go to the product page. Considering inventory option has a bug and hence I have to change around 50 products, I was hoping at least thisoption would be there. It isn't.
Seems like Marketpress, although adding inventory as an option, does not give it enough importance. Please note, it is one of the most important features for an ecommerce site.
So I am hoping this gets implemented.
