Magento Dev Tool: Allows you to easily and quickly show/hide path hints when enabled in Backend
This is a "dev tool" for Magento. It allows you to easily and quickly show/hide "Template Path Hints" and "Block Names" (when enabled from backend/admin area). It does so by searching the DOM for particular style attributes and updates the them furthermore. For re-enabling a previously set unique name is searched and updated again.
Tested so far in Magento Community Edition 220.127.116.11, 18.104.22.168 and 2.1.
