Change Product Edit Form

How can I change the layout of the Product Edit Form?

For Example, I need to make some fields mandatory (specially the features fields)

Also, I need to bring them to the General Tab, so that the user use it quickly and I need to hide other tabs and fields that are not needed (at this stage of the project)

In the attached layout, many tabs and fields that I don't need now. How can I hide them?

Is there a way where I can change the layout and behavior of this form?

Copy design/backend/templates/views/products/details.tpl to design/backend/templates/addons/my_changes/overrides/views/products/details.tpl

And adjust to suit your needs.

Check forum for themes where ability to hide fields/tabs was discussed for vendors. You can use the same logic for CS-Cart admins as well
