As someone who very occasionally gets into the nuts & bolts of WP, I know I’d find it handy to have a link show up with the error (slug already in use) that would take me to where the preexisting slug is, so I can decide whether to change the preexisting one, or select something different.
Frex: my trash is empty, but I get the error when trying to create a new tag, & can’t find where the original slug is.
Or maybe there’s a way I don’t yet know…?
