-## Checklist
+- See comp images in Breadcrumbs component directory for visual improvements
 
 - Text code blocks have weird formatting: `src/content/articles/cdn-edge-caching-cache-keys-vary-headers/index.mdx` that one seems like it should be some other kind of display, not a text code block.
 
-- You can click the anchor link that shows on headers to get a copy of the link. It should be that you can click anywhere in the header and copy the link.
-
-- Need to make tables responsive on mobile
-
 - Need to stop system from adding abbreviation html when used in headings, also the `abbr` presentation needs improved - right now it gives a question mark pointer and long delay to appear
 
 - Re-enable link validator in `astro.config.ts` when pdf / downloads sorted out
