I've created an option under System > Configuration > Catalog > Catalog that allows an admin to select which customer groups can add products to the cart. I now want to notify admin's about this setting when they are changing wishlist settings on another system config page. Something like "Products in the Wishlist can only be added to the cart if blah blah blah."
1) I know about the <depends>
tag, but I don't know how to use that for settings from other parts of the config. For instance <depends><active>1</active></depends>
is simple, but how can I do that for fields from other groups or sections?
2) Is there a standardized way to put a notification or simple string on a system config page, or does Magento only support fields out of the box?
Thank you.
