what purpose does :ui/fetch-state serve in the pagination example in the book? I see that ui bits are typically used to mess with front end stuff, but I don't see the use case for it in the example.

What's the use for co-located CSS? Tried to google for that and didn't find much.

Tip: If you use https://blog.jakubholy.net/2020/troubleshooting-fulcro/ remember to refresh the page regularly, I update it +- frequently.

@tony.kay here https://youtu.be/P2up8qcDmJs?t=1644 you define the all-widgets as a defattr, saying that it could also be just a resolver but that by using defattr you sometimes get some other things out of it. So when would you recommend using defattr vs defresolver if I only need the resolver, i.e. if I don't need to use it as an attribute on a form/report? Thank you!

defattr is for most cases. I use defresolver for top-level keys, like the entry point of a report, since you never need to augment that with anything. You can also make a defattr and a resolver, which might be good if you are for example using pathom 3 with current RAD, or pathom 2 with some future pathom3-based RAD.

(or you want to put resolvers in CLJ file instead of CLJC)

that last reason is probably most salient right now @holyjak, since resolvers in attrs always lead to a bunch of conditional CLJ
