A look at Amazon Prime Video’s code shows that Amazon is building one of the best YouTube TV features: multiview. It would literally be a game-changer for one of the top streaming services.

The potential new feature was spotted by Android Authority during one of their regular APK dives. In the latest build of the Prime Video app, version 3.0.389, they discovered code strings such as “exit_multiview_text.” Based on these strings, it appears that Amazon is working on a version of Multiview that will allow viewers to customize what appears in the different boxes.
