Magento – enable admin template path hints
Path hints is a very useful tool for Magento Theming as it let us know where exactly we have to go.
It’s easy for front-end to enable the path hints and locate the template file because it is available by default but it is not set up for Admin area.
To add option for Admin path hints in configuration page we need to hack the core code.
find the file in app/code/core/Mage/Core/etc/system.xml and copy it in app/code/local/Mage/Core/etc/system.xml. It’s a good practice to always duplicate the core files in local directory.
Look inside the Debug section, there will be label “Template Path Hints” and “Add Block Names to Hints” set 0 (zero). Simply change it to 1 (one).
