I've used /YYYY/MM/slug for my URLs for as long as I can remember. In Kirby, it feels like a bit of a hack, so I've decided to abandon it. I'm now using native Kirby URLs for posts, e.g. "/posts/YYYY/MM/slug". No more magic. I do, however, redirect from /YYYY/MM/slug to /posts/YYYY/MM/slug so that old URLs should still work. Let me know if you notice anything broken
