On the PS3, when playing media within My Media, I can hit play on the first track of an album (or the first video in a given folder), and it when the first one ends, it will move on automatically to the next file.
Within the mobile app (at least the Android app), this does not happen. I have to back out to the file list and manually select the next file. This makes playing albums of music, or TV series difficult and clunky.
Ideally, I would love the ability to create customized playlists directly within the mobile app, and then have playback options such as randomize, repeat, etc. But at its most basic, I would really like the ability for the mobile app to simply move on to the next file within a given My Media folder.
