How to display 'length' in tag panel?

I'm trying to figure out how to view the bitrate and length of a song without having to scroll to the rightmost columns in the main window. Specifically, I'm trying to display the length and bitrate in the Tag Panel.

I did the following:

  1. Went into Options > Tag Panel
  2. I tried adding a new field, with the field value being "LENGTH" (also tried "%_length%" with and without the percentage symbols). The field is added but is always empty, even thought the 'length' column in the main window shows the length.

There are 3 other optional Tag Panel fields (specifically: Album Artist, Composer, and Discnumber) and those are displaying the values ok.

Any ideas what I'm doing wrong??

Also, I've never had the 'display cover art' box show any covers, but that's a separate issue I'm sure.

Thanks in advance for the help!

I think i read somewhere here in the forum that information fields which are no tag, like %_bitrate% and %_length%, can't be shown at the tag panel.

You can move the columns to the left to see them faster.
The length is also shown at the status bar down right when you mark individual files.
