It would be helpful if there were labels on the notes in the title notes tab in the opac. It can be confusing sometimes what the notes you're looking at are when there are a lot of notes (5xx fields).
As I said in Bug 13269, all of the 5xx data is dumped into the descriptions tab without any parsing at all. That is, Koha doesn't examine which tag is which when being displayed. In order to make this work you'd have to either hard-code a template with all the possible labels or pull from the framework tag descriptions--which would make them untranslatable.
