In this chapter, we learned how to modify and extend the Magento backend to our specific needs.
Whereas, the frontend extends the functionality that the customers and users can use; extending the backend allows us to control this custom functionality and how customers interact with it.
Grids and forms are important parts of the Magento backend, and by using them properly, we can add a lot of functionality without having to write a lot of code or reinvent the wheel.
Finally, we learned how to use the permissions and Magento ACL to control and restrict the permissions of our custom extension after extension, as well as Magento in general.
In the next chapter, we will dive deep into the Magento API, and we will learn how to extend it to manipulate our registry data using several methods such as SOAP, XML-RPC, and REST.
