Great plugin and free as well, brilliant deal. I am using Rank Math Pro which has a redirection feature but it was having trouble with my 404's so I installed another plugin to redirect to my "clever" 404 page. I have disabled auto redirects in Rank Math Pro now and uninstalled the other 404 plugin.

For onboarding, I would suggest allowing the plugin to import redirections from SEO plugins like Rank Math Pro, SEO Express and Yoast. SEO Express and Rank Math have this feature on the initial setup and it's nice. Also, allow bulk editing of redirects for options that could be executed in bulk like changing the types, enabling/disabling and deleting.

Otherwise, I've spent about 10 minutes on the plugin, and it seems to be doing the job.
