Add/remove Product Page Areas

Hi

On the following page vendor.php?dispatch=products.add

I would like to remove some fields as they are not required. How is it possible to remove pricing/inventory section ?

Also how can the tab 'Quantity Discounts' be removed?

Thanks

Template:

design/backend/templates/views/products/update.tpl

Controller:

app/controllers/backend/products.php

Changes required in both files

P.S. It is recommended to use addon with post controller and template override

Suggest you use an override for the update.tpl file so your changes will survive an upgrade and that the controller you use is a local controller like my_changes/backend/products.pre.php for the same reasons. But you will want to be sure to compare your override version of update.tpl against any new versions that are installed to ensure you pick up bug fixes or other changes that may occur at a newer version.
