Possible implementation for sorting on ID3:

contents of .pythmrc:

ID3Sort={%artist - }{%year - }{%album - }{%discnumber}{%tracknumber
}{%title}{ (%length)}{ %genre}{ %rating}

or also possible

ID3Sort={%a - }{%y - }{%b - }{%d}{%n}{%t}{ (%l)}{ %g}{ %r}

The ID3 tag with extra surrounding characters in between the {} will not
be displayed when the value is not set (Null of empty string). This
entire ID3Sort definition will be read on startup of pythm and will be
used for sorting tracks.

The tags used in the definition also dictate the order and contents of
the columns in the overview. In this case begin:

Artist, Year, Album, DiscNmbr, TrackNmbr, Title, Length, Genre, Rating

Possibly a second definition in .pythmrc can be used for custom column
order. e.g.:

or also possible

In this example disc number and track number are combined in the same
column and will simply be concatenated. The header will be emtpy of on
detection of this special case be simply 'Number' of '#'

Also to customist this, a third definition can be specified. e.g.:


And at the same time this third definition allows for localisation.

So the use of the following optional definitions in .pythmrc:
which are customised by the user will allow for ID3 sorting and
presentation catering everyone's wildest ID3 needs.

More people interested in implementing this?
