I install this plugin on every WP site I develop. It really helps out considerably -- tracks 404, set up custom redirects, automatically redirects if pages' slugs are renamed -- so convenient!
I did have some issues in the beginning as I was learning the plugin's capabilities -- accidentally made some infinite redirect loops a couple times, oops haha -- but now that I have all the tricks figured out, it's a breeze and a real time saver.
Love it! Thanks for creating & sharing.
