The user experience of using the Accessibility tags feature is unacceptably inefficient. Consider that the user might need to tag hundreds of documents, themselves hundreds of pages. Try this yourself, or observe someone else trying it. You should quickly see how unnecessarily slow and tedious the workflow is, using these tools. Dragging little tiny icons around in the sidebar panel is slow, difficult, and often inaccurate. There's no way to just click on something on the screen to indicate what it is and how it should be tagged. You can't draw an area around an image/caption. When the auto tag thinks it has identified a paragraph, often it's several paragraphs or parts of one, and there's no easy way to clean that up. It simply isn't usable for any real work in its current state.
