I really like a breadcrumb plugin that I tested out for Wordpress (it adds link navigation like Home > Cars > Toyota to your pages), but the links point to WP categories, rather than pages. For instance, using the example before, say that I have a page for "Cars" that was custom made, and one for "Toyota" that was also custom made, and I want the breadcrumbs to point to those instead of the worthless default WP categories. Is it wise to 301 redirect categories to pages in this case, or will that create problems somehow, down the line?
