First off, this program is a God send, so great work!
I have searched this site and read many pages and cannot find exactly what I want:
I'm using v2.36a, which I believe is the latest...
Ultimately I need to be able to include the Length value in the Export function, and see in the tag panel (not as important as being able to include in Export).
When I add tags, (Time or SongLen), close and reopen Mp3tag, there is nothing listed in those added fields on the left-hand side tag panel when I select songs (i.e. - everything else changes accordingly 'Title, Artist, etc...' but nothing appears in the added fields.
I'm assuming that track time (Length) would not export for all tracks either.
Please advise.

For the export, just use the field **%\_length%**
You can also look in the help file for more fields.
The tag panel is only meant for tag fields, not technical information.

Beautiful ...thanks!
Brain cramp, but now I know to edit the config files to get results!
I was looking for options in program menu, etc..
Looks great.
