As someone who's never taken notes while listening to podcasts, I'm curious what your use cases are. Do you listen as part of your research for a project?
I think most people listen to podcasts for fun and entertainment so it's unlikely they'll want to clip, get transcripts etc. But the small number of podcasts doing deep dives on scholarly, technical or professional matters? It's potentially quite useful to be able to get transcripts/excerpts with highlights and audio clips to add to personal notes for future reference.
