I would like to have following features:
in 'Filename to Filename' patterns I would like also to have possibility to use tag's fieldnames. This would give me a possibility of powerful filename edition
I would suggest also to define %playlistpossition% variable - this variable would hold possition of file in the playlist.
What can it be used for? For example we want to rename all the files to be in the same order as in the playlist - I miss this feature very much.
