There are two ways to edit tabs on the product edit page, the first few tabs are controlled in the order of the attribute group (as Matthew pointed out). The second piece of tabs is added directly to the code, adding a tab to the block.
Thus, there are two ways to change these tabs.
- Change the order of attribute groups in the attribute set (using the graphical interface)
- Extend the Tab block, Core / Mage / Adminhtml / Block / Catalog / Product / Edit / Tabs.php and manually reorder the tabs.
Inside the block, you can also add your own tabs using $ this-> addTab ()
