Hi AbanteCart
How i can add a new Parent Menu on the admin sidebar under Design menu.
Admin menu is constructed in the dataset tables structure
Check this manual:
http://docs.abantecart.com/pages/developer/developing_extensions_and_extension_api.html
Admin menu can be inserted only programmatically.
See this extension as example of how to add menu item
