At the moment, the playlist catalogue just includes all playlists it finds in the top-level of the 'playlists' directory. I was thinking it would be useful if it would look further down the directory tree from that folder, when finding playlists (just looking one subdirectory level down would be very useful). Because that would make it easier to organise playlists when you have hundreds of them. When displayed in the playlist catalogue the path could be pre-fixed to the playlist name (in case of duplicate names).
Doing this would also mean, when looking at playlists through the 'files' option rather than the playlists catalogue, to locate specific playlists more easily, without having to scroll through a huge list.
So one could have a folder for playlists themed by 'mood', another by 'artists' another by 'era', and so on. I'm thinking more of playlists created on the computer and transferred. At the moment I tell media monkey script to prefix words (like 'mood' or 'era'...) to the playlist name, but it would be better if one could use a subdirectory.
Playlists created on the device itself could just go into the top level directory, or a particular sub-directory ('UserCreated' or something)
Was looking at the code myself, but not sure i'm up to the job.
