That idea occurred to me while editing my guides. If there are new deck-guide features being implemented over next site updates, I believe this feature should be considered. We use tables and scripts such as cardimg, yet we can only see our "real template" after deck-guide is saved. If we don't like it, we need to edit a guide over and over again, which can be time-consuming. What if there were "Preview" button that lets us have a look briefly, so that we can save only once, rather than multiple times?
