Alan, you might like Multi WP Blog search from a while back. Local storage could make it actually useful.
4/15 #HeyPresstoConf20 For fun try adding /wp-json/wp/v2/posts/ to any WordPress url or /wp-json/wp/v2/posts/?per_page=1 will get you the latest post or /wp-json/wp/v2/comments for 20 recent comments or /wp-json/wp/v2/search?search=splot will return search results for "splot"
This is nifty John, I can see all kinds of things you can do. Options for number of return results, excerpt, thumbnails…
Thanks, your #HeyPresstoConf20 reminded me an reignited some thinking:-)
