Provide a visual reference to Marketo's guided landing page templates

Now that the list of templates (Guided Landing Page Templates - Marketo Docs - Product Docs ) continues to grow, it would be useful to see what each template looks like without having to click each and every one.  In addition, it would also be helpful to determine what the differences are between the "letter" variations within each parent (e.g., 15A, 15B, 15C, 15D, 15E).  It's not apparent when clicking on each.  It probably would be if there was a visual reference to compare each against.
