I think the elisp package 'macrostep' really gives legendary inline macroexpansion. cider-macroexpand-1-inplace on it's own is spartan, which is good but macrostep with it's overlays is totally smooth. -> ok I found somebody made this work https://github.com/clojure-emacs/cider/issues/1850 this is basically what I wanted. Only thing missing at first glance is the colored gemsyms

is there a way to get cider to report to me that I have a source file using a function that is defined in the same namespace, but not actually in the code any longer?

clj-kondo should handle that
