Love the app! I use it on my iPhone.
I would love, love, love to be able to transition into a whole new Spotify playlist from whatever is currently playing, but everything I've tried immediately and abruptly switches to the new playlist. I'd like to add a new playlist in the same way that you can currently add a new track to a mix. I don't care if that means the rest of the current mix disappears. So I suppose that could mean building on the capabilities of the current 'add track' feature or adding a whole new function designed specifically for this purpose.
Thank you for your consideration!
