Hadn't even thought of that! it's a good idea, but i don't know how i'd
present it in the interface... Also i'll have to have a look at how
gstreamer handles this.

Not sure what you mean by searching, on the device? There has been a
suggestion (for devices that support it) arranging songs into folders by
artist. There would also probably need to be an option to keeps songs
sorted as they are. e.g. if the user had already sorted the files into
folders, these folders should probably be recreated on the device.

Sounds good.

Perhaps for playlists (on rb) specific to a device it can show the free
space and the capacity of the device on the status bar.

I like the idea of the device automatically syncing to the computer,
copy songs added to the (rb) playlist to the device, copy songs from the
device to some folder and add to (rb) library and the playlist. Remove
songs from the playlist if they have been deleted from the device.

I'm not sure how to do this. Identifying devices (at the moment) is done
through hal which has a file of usbids that correspond to mp3 players.

Another vote for immediate. That clinches it. By eject i meant "make
safe to remove", but i think g-v-m mounts all storage devices with the
sync option anyway. But it looks nice to see "Removable" (or some such)
on the device to know it's safe to unplug.

Sounds good, i'm currently writing up a first version and i'll let the
list know of my progress.
