The directory has a significant flaw, that besides sorting it does not let you do anything. Many times I would like to understand which pipelines people are in, but it does not let me filter pipe pipeline or sort that field. A simple has value/has none, would be already sufficient...
Thank you for sharing your feedback with us! We'll definitely keep it in mind for future updates to improve the directory. If you have any more suggestions or questions, feel free to reach out anytime.
