Please note: This idea only applies to Spotify client version 0.8.8+
I will admit this is partly my idea, but it has also been pointed out many times on the "Horrible Update" summarized nicely by Premify here.
I would really like the ability to view all of my playlist followers and I am sure I am not the only one. What I am suggesting is a simple system, where you could press on the "# Followers" section of the playlist Window:
I would suggest it would either give you a drop down of all the followers or even better (in my opinion), a redirect to another page with all the followers on it similar to the Following/Followers tab in the Follow page of the client.
