Adds a button to Amazon book pages to redirect to Goodreads page based on ASIN/ISBN
Reverted back to old code and just added MutationObserver so button shows. Then I noticed even older version was showing button on non-book pages. So I added a check for Publisher Date before button is shown. This seems to be easiest way to only show button on Book pages. Let me know if you have any other problems.
Its working good now with one caveat. I explicitly need to change this part `// @match https://*.amazon.*/*` to `// @match https://*.amazon.com/*` for the button to start appearing in the first hand. Probably due to @match not supporting such a scenario (https://github.com/Tampermonkey/tampermonkey/issues/1878)
Changed and update code back to how it was before with multiple domains listed. I use ViolentMonkey and it worked find on that. Hope this helps.
All good now:)
The latest update seems to make the button visible on all amazon product pages & not just books pages. Just wanted to check and see if some simple fix to this can be arranged...
