More Fields is a WordPress plugin that adds boxes to the Write/Edit page. These boxes contains input fields, so that additional (more) fields can be added to a post. For example, if you write about books, you can add a box where you can enter title and author, etc. The boxes can be placed either to the right or to the left on the Write/Edit page. In addition, the new version of More Fields enables you to define post types, which are custom Write/Edit pages that contains a pre-defined set of boxes. For example, you write about books and you write about your holidays, then you can define a post type 'Book' and a post type 'Holiday' each containing the input boxes relevant to each type of text. You can also set pre-defined categories, tags and templates for each post type.
