i have been meaning to do basic track name/time matching for a while now, so i did it this afternoon. i've posted a version at
http://groups.yahoo.com/group/xact-usersthe interface to put in track times is ugly, but it works.
if you want to put in track names, you click the "names" button to bring up the input window. write in track names, with each on a separate line. click "done" to save the setlist.
then, if you choose to get your "shntool len" information parsed by disc or fileset, xACT will match up the track names and times for each file, with each line having the same amount of characters (when viewed in a fixed width font, the times will all line up)
most of the info file work all done for you...
