Having seen Huh in action for a bit, I think a good improvement would be to eliminate the focus indicators when they're implicit, with the goal of making the experience more visually focused and concise.

In other words, I don't think we always need to draw the little bar that indicates the active section in all cases.

Off the top of my head, the logic would work like this:

1. If the entire form is one single field, hide the indicator.
2. If the entire form has multiple groups with one single field in each group, hide all indicators.
3. In all other cases show the indicator.
