I’m not whether this is proper sequencing or a bug, but I thought I would report. If I delete tracks from the DB, the numbers are not reassigned when new tracks are imported into mAirList. For example, if tracks 1-20 are deleted from the virtual folders, the numbers 1-20 are never reassigned. Instead, the new files are given new numbers at the end of the file numbering sequence. Should the numbers 1-20 be recycled or is this proper behavior?
