Hi. The plugin works great, but I think it lacks an essential feature: search. Because sometimes you need to change the name of permalinks, posts or categories, and then the plugin will log hundreds of 404 errors. And it would be nice if in the lists of automatic redirects, manual redirects, 404 captured errors and so, you include a search function or some kind of filter so you can reduce the list to a given pattern. Otherwise, managing the lists is a slow a painful task.
Hope you can implement it soon. It's easy, as it is just a filter in every query ;)
