Sorry you don't love the new viewer. The purpose of the name panel on the left is to help you keep your context when you look farther to the right on the document where the names aren't visible, not necessarily to show you a transcription of the names. It also shouldn't be appearing until you've started panning away from the names (the names column starts to go off the left side of the viewer) so zooming in on the names generally shouldn't activate the panel.
In any case, feel free to turn off this feature by clicking on "Show name labels" in the Image tools menu. Unfortunately we don't remember those preferences yet from session to session, but we'll be updating in the next week or two so we remember user preferences for optional features (so you won't have to turn off name labels each time you visit).
