Wonderful module!
Forgive me if I've misunderstood, but it seems that if I wanted to utilize a given group of tabs in exactly the same way on various pages, except with varying tab labels on the respective content displays, I would need to additional field groups tailored to each specific page. This is the behavior I am seeing here, anyway. It would be better if I could label the tabs within the page content editing instead of hard coding them, so to speak, in the content type area.
For example, a page about a species of mammals might display tabs labeled as "Diet", "Habitat" and "Physiology" while a page about cars might be labeled as "Fuel Considerations", "History" and "Makes and Models". Maintaining a single set of fieldgroups and picking the actual tab names in the page content would entail less setup and administration, assuming the chief differences between each page are the tab names and the content displayed within each tab.
