Is there a way to remove the 2 Craft specific menu items from Redactor's Link menu without losing access to the "Insert link" menu item?
Removing the Link button in the redactor configs is too draconian as I don't want to lose access to the basic Insert and Unlink functions previously in that menu.
I've dug into the src, and the only hook/event I can find related to the redactor settings allows addition of menu items to the Links menu, but not removal of the Craft added "Link to an Entry" and "Link to a Category".
