I'm new to hemingway and still learning my way around wordpress in a lot of ways--anyway, I'm using widgets on another blog and just started a new blog with the hemingway-based u4 theme. It has a hemingway bar in the hemingway options that lists the blocks in the 3-column footer area. They're draggable and look like widgets, but instead, you can't click on the titles to set options like you can with widgets. So does anyone know how to change the text or configure what's in those blocks? Can I also install the widgets plugin and use that? Can I add new types of blocks like you can add new types of widgets just by placing the widget in the widgets folder?
