I was under the impression that when the <Untagged> item appears in a Database Browser list, it would always be pinned near the top of the list, just below <All tracks> and <Random>. But I have encountered two situations where the <Untagged> item is apparently getting alphabetically sorted into the list. In the attached pdf are two screen dump examples, and here are the lines from my tagnavi_custom.config file that generate them:
"Album" -> album ? filename ^ "/_otherLIBs" -> title = "fmt_title"
"Composer" -> composer ? filename ^ "/_otherLIBs" -> album -> title = "fmt_title"
