I also listen to shows that aren't carried locally, and of course, time listening through the NPR app is time not spent listening to KUT directly (which I probably would do if there weren't alternatives, because I'm pretty much an NPR junkie).
This new app seamlessly mixes in content from your local station and features the local content prominently.
I think they have done a fantastic job here and are working hard to do good by their local stations.
Just glancing at the app, I don't think there is anything here that you couldn't currently do in the NPR app ecosystem. For example there is already an NPR app that lets you choose radio stations or just programs from around the world and a lot of local stations built their own, independent app (though in my experience those are lower quality)
