Isn't that what the editor is that I mentioned? If you go to the genres tab, tap a genre to view it then tap edit, there is a whole editor just for adding/removing/renaming/reordering.
If you meant that you would have expected to have a way to access an editor like I described for any group type listed in the song editor, or envisioned a different workflow, I'm always curious to hear ideas for potential changes. The main purpose of listing the fields in the song editor was so that users could quickly add or remove a song from a given group. The intention was not to provide an indirect pathway to editing the groups themselves (which is what the group editor is for).
