Drupal - Jump for joy, or off the balcony

Drupal alternatively makes me want to either jump for joy or jump off the balcony. Today was a balcony day.

Today’s issue is related to the handling of “tags” in Drupal 8, specifically the issue where you can’t add a new tag when editing a blog post, you can only reference existing tags. I have a degree in aerospace engineering, founded and sold a programming business, and can write software in many different languages, but a few things like this in Drupal make me feel like I need more of an education.
