A request for Genre/Subgenre handling

[Peter@57m]

Is there a one to one match between Genre and Subgenre? If so, I think Subgenre will not appear - see part of the manual below

'One or more tag choices. Each of these choices is displayed as a tag name such as Artist, Genre or Conductor. The tags displayed here are those that apply to one or more items in the current selection but don't apply to all items in the current selection. If you select one of these tags, you'll see all the values for the selected tag that are available in the current selection—for example, selecting the Artist tag will show all available artists. You can select any of these tag values to create your next selection.'
