This plugin is simple enough to use: Just put the "from" address and the "to" address. I recommend that both be relative to root.
It's good for redirecting old pages, but it also helps with scenarios like this: I wanted to redirect users from "/categories/news/" to my page at "/news/", and this plugin worked well.
Works for me with WordPress 3.7.
One suggestion: Please add a "description" field for the redirect entries. Redirects can become numerous, and it would help in keeping them tidy if we had notes as to why we did a certain redirect.
