HTML Source Button Buried in New WYSIWYG Email Editor

The new toolbar in the WYSIWYG editor for email production looks great, but most of the features are now buried under the "More" button, which requires an extra click. Can the HTML source button be added to the primary toolbar, and not beneath the "More" button? It's a commonly used feature that allows access to more advanced editing, and it would keep things more efficient for power users!
