The transcript feature is a huge improvement to the Apple Podcast app. Unfortunately, they chose to not let us save the transcript. And, they only allow copying (to paste) a few paragraphs at a time. With many of the high-value, dense information episodes, it takes some serious concentration and reading is more suitable for comprehension. The small screen isn't my preference. I really want to save the transcript and read it on my larger laptop or maybe tablet, and often share the transcript with a friend/colleague.
Good start, I hope they take the idea all the way.
