The author built a heuristic based on 'equiv' doc metadata and function specs to decide when to merge signatures or types, with a fallback to standard ExDoc output when the heuristic fails. A generated preview of Erlang/OTP 29.0-rc2 docs with this feature is shared for community feedback on whether the more compact format is an improvement. ## Full article daily.dev links to this article rather than hosting it.
