is it ok/possible to call/transact a mutate method from another mutate method? Let’s say I have defmethod mutate set-a-thing! and then I have defmethod mutate set-many-things!. Can I execute first one multiple times from the second one?

@ag seems like that would be fine, I think I do that in a couple of cases

My own question: I'm still trying to wrap my head around the uses of Ident declarations... if an app is not using normalization, there's still a benefit to declaring Idents to optimize rendering, is that right? Is there any good resource that explains this? (or maybe just a section of the OmNext source code that I should grok to understand this better?)

@drcode i give everything an ident whether i use it that way or not... not sure if that's the best way, but is clearest

@tony.kay an open question (as in anyone can answer) about the much use of factories here on line 52, looks as if each list item in a dropdown menu is an react component on its own. Just a stylistic question rather, what are to pros of mapping data to a component that does not much else than render, vs just map the data within a render method of a component. My projects tend to be few massive defui, I wonder what is more readable, maintainable etc... Ps the defmutation macro is very sweet!

@hlolli: you're often better off in the case I'm showing there with just a function unless there's some need to do mutations on the items, or you want to share them. I split them there more out of habit than necessity. If your query gets too hairy you can experience performance problems.

Either way it's easy to convert back and forth as the need arises
