One thing that might work instead of the options page to help folks is a "suggestion" screen where the plugin shows one tag at a time and returns a list of wikidata items that might be relevant. The user could choose to associate one of them, or skip to the next tag.

Hi! Apologies that it's taken a while for me to revisit this and provide thoughts and feedback. Thanks for working on this, I love that this is coming together!

Ah yes I see what you mean :)

Hi! @Pigsonthewing asked for my feedback on this as I'm a WordPress developer, and I'm happy to help.
