Want to add a section in Magento system configuration? It seems very easy as mentioned by others. No coding but editing xml files. Magento takes care of the rest. However, it still took me two hours to find the way out. So I think I need tell the world the caveats.
- A section will not be shown if it is empty (no fields inside). Ditto tab or group.
- acl must be defined per section in config.xml, otherwise you get Access Denied message.
- Re-login is required, otherwise you still get Access Denied message.
