As the current Spotify app stands a tab bar navigation would make it easier to navigate but it’s not easily scaleable. I believe they could do one of two things.
- Adopt the the last tab options as a over flow screen.
This would work like the facebook app. (See image below.) All the small extras of the app will be located here. Settings, profile etc.
2. The second option is to go more of a tweetbot style menu. This is extremely limiting. (See image below.)
