Oh, and when it comes to the media player, aside from portrait mode, offhand the only major thing missing for my use cases is built-in editing of file metadata for MP3s, Oggs, etc. That'd be awesome.

Perhaps some kind of simple shoutcast browser might be useful too, for finding web radio stations.

It'd also be kinda cool to add in more formats, a-la Winamp plugins. I'd like to be able to play things like C64 SID files via the media player, but I've no idea how it manages it's codecs. I know the OGG Support package does that, so perhaps it's nothing you need to concern yourself with (and something I should look into myself), but worth an ask.
