This lets players that can't spare any keys scroll through
albums without leaving the track listing first, which was
only possible on the M3K before.
Enter mode from Main Menu. While active, the gradient
highlighting an album's selected track will not appear,
and context menu options apply to the whole album
instead of to a single track.
Exit mode by pressing buttons for Select/Back, or by
quitting PictureFlow.
NB: Be sure to enable "Database in RAM" for a good
experience, as the loading time for each album can
become quite annoying otherwise.
