Although Miro boards may look like cute folders on your homepage, they actually don’t support a folder system inside. Everything you add is displayed directly on the board rather than as small icons. For example, a 20-page document appears like 20 individual images laid out on a table. That’s not a problem by itself—but just one book from the NGL Life series has around 400 pages. So if your goal is to build a full library, you’ll want to avoid turning your board into something resembling a conspiracy theory.
