I am very pleased with my V2 pogoplug and the "automagic" discovery and organization of media files.  And of course I want more. 

Specifically:

    1) Use more than one filter at a time.  For example, with music files it would be nice to be able to choose a genre, and then once again have the choice to filter/display by artist, album, or song, instead of just having a list of all the songs in that genre.

    2) Allow the user to create custom tags and filter by them.  These tags would probably be stored only within .cedata and not within the actual file.  This would allow the user to create photo albums, song playlists, etc. but also would allow them to group non-media files, if extended to them.
