A change in the upcoming update is that Mizuu will automatically download the most popular backdrop image to your device along with the cover art image, if such a backdrop image is available.
The next update will put more focus on backdrop images, especially on smartphones where the details view will show just the backdrop image and not the cover art image. If no backdrop image is available, it’ll still show the cover art image, but that naturally won’t look quite as good.
Here are a few screenshots of what the movie details view looks like on a tablet and a smartphone:
PS. It’ll of course be available as a setting as well, so you can turn it off, if you don’t want Mizuu to download backdrop images. It’s highly recommended though and backdrop images don’t take up much storage space.
PPS. Notice that “eye icon”? That’s a drop-down to mark movies as watched or to add them to the Watch list. Do you think it should be visible at all time or should it be accessible from the overflow menu?
