Summary: Generates navigation bread crumbs in WordPress. Requires permalinks.
A client of mine was using the Simple Crumbs and it wouldn't work once PHP was updated on his server. As Simple Crumbs hadn't been updated since 2009 and I needed to get my client going, I just created Simple Crumbs Redux and got him going. I made a few minor improvements over the original plugin and will work as a drop in replacement. Whether I add any other features depends on my needs and if I get any requests from users.
