That sounds great! I’m envisioning something that for each loaded namespace would show:

  - fns that match saved files
  - fns that differ:
    - newer in file / not in REPL
    - newer in REPL / not in file

I guess that would have to be an IDE-level thing, since it needs to know about file changes and REPL contents.

A namespaced list of all public var names can be thrown together pretty quickly, but it seems less helpful:

(->> all-ns (ns-name) (map (juxt identity clojure.repl/dir)) (into {}))

(I’m on mobile so I haven’t checked that!)
