Specifically, I think best practice ought to be to have a separate template for each tab. Then the connector code can call all the templates one after another. It makes it easy to add a tab, and easy to maintain.
Each template, then, becomes responsible for managing both the tab in its hidden form, as well as the tab in its displayed form.
We can do something similar for the "view" templates.
