Problem: The problem is that some wikis use both; the classic way to mark references inside the article text, and the other way, list-defined references. The latter can't be edited with visual editor as references are marked inside the references template. This makes it difficult for those who use visual editor for editing. And those who primarily use wikitext editor, they don't like "the mess" when there are many citations next to each other in article text because it makes editing more difficult.
Proposed solution: Add a button that hides and shows references in article text when you click it. Only leave the reference name <ref name="xxx"/>. At least this would help some editors.
