Thanks @claudiu - yes I did come across that page trying to understand what #om-next was doing - but the page doesn't reference the :value {:keys [:todo/list]} option from the om next docs, which made me wonder whether it was not used. Yes, I have looked at Fulcro a few times and might use it for the next project. I can see that Tony has rewritten the relevant parser/mutation from om-next https://github.com/fulcrologic/fulcro/commit/a8cd1ea3b1c2ed616814b011b5fe7a4bb0dcd30c

@felixb Yep. Fulcro has gotten about 6 months full-time from Tony last year. Crazy amount of improvements. Think the best place that highlights this is the https://www.patreon.com/fulcro/posts page
