Me and my friend had a great session in the car the other day. We queued and played songs during a quite long ride. Afterwards, I was absolutely sure that I could find the history and save it as a playlist - but I was brutally disappointed. No such feature at all even though I know Spotify has my queue in their vaults. I mentioned this to another friend that had the same experience after her friends went mad at a party and played beatiful music all night long - which she wanted to turn into her memory of the party.
So - please implement a feature that digs up the most recent queue and saves it as a playlist.
