It may not really matter to many people out there, but many times our clients want a customized look for their Magento Admin. For instance, how do you change the title of the Magento Admin section pages from “Magento Admin” to “Your Company Admin”?
As always BACKUP YOUR FILES!
Well the file is somewhat hidden, but not as much as many things with Magento. Go here: app/design/adminhtml/default/default/layout/main.xml
You’ll find the page_head code that reads <title>Magento Admin</title>
Change that to <title>My Company Admin</title>
Save the file. You may have to refresh your cache in Magento admin.
There you go, there’s the first step of how to change Magento Admin to My Company Admin.
