Maybe a bit off-topic: the current version of MP3Tag will not convert the tracks from one digit to two when generating filenames (using Tag - Filename). Is it possible to have the old behaviour back?
If you don't understand what I mean, here is an example:
> [@](#):
>
> Track: 5
> Title: Bubu
> ...
> Filename (using "%n %t"): **0** 5 Bubu
> [@](#):
>
> Track: 5
> Title: Bubu
> ...
> Filename (using "%n %t"): 5 Bubu

Sebastian,
IMO the old behaviour is not very logical, because it always exports tracknumbers with leading zeros and doesn't care about the track#-format in the tag.
I think a build in scripting function like $num(x,y) for Tag - Filename, which returns x as decimal number and pads with zeros up to y characters is more flexible.
With best regards,
~ Florian

Current development build ships with $num(x,y) scripting command 🙂
