Magento Template Path Hints in Admin - Updated

A while ago we posted a technique for displaying template path hints in admin which involved running a couple of DB queries. That worked, but a nicer method is to create a custom module with some special XML config to get it configurable as standard.

<?xml version="1.0"?>
<config>
    <sections>
        <dev translate="label" module="core">
            <groups>
                <debug translate="label">
                    <fields>
                        <template_hints translate="label">
                            <frontend_type>select</frontend_type>
                            <source_model>adminhtml/system_config_source_yesno</source_model>
                            <sort_order>20</sort_order>
                            <show_in_default>1</show_in_default>
                            <show_in_website>1</show_in_website>
                            <show_in_store>1</show_in_store>
                        </template_hints>
                        <template_hints_blocks translate="label">
                            <label>Add Block Names to Hints</label>
                            <frontend_type>select</frontend_type>
                            <source_model>adminhtml/system_config_source_yesno</source_model>
                            <sort_order>21</sort_order>
                            <show_in_default>1</show_in_default>
                            <show_in_website>1</show_in_website>
                            <show_in_store>1</show_in_store>
                        </template_hints_blocks>
                    </fields>
                </debug>
            </groups>
        </dev>
    </sections>
</config>
