Works great, thanks!
Maybe you could implement this feature if you would mention in the admin that cache is automatically deleted for posts that are edited or commented on. I think it would actually be good for UX if you see the reassuring explanation that the cache for a specific page is deleted when something ‘happens’ to that page. You could then add in an mention for the front page as well.
At this moment, you can only tick the option for complete cache deletion for new posts, not for modified posts. Single cache deletion of course happens automatically when a post is edited or commented on, but you can only tell if you test it first on your site (or read the readme, which nobody ever does).
Just some feedback, take it or leave it ??
