The Tabs module provides a set of APIs for working with tabs. Currently at least three modules use the Tabs module APIs:
While quicktabs began as a quick way of placing tabs on blocks, it's grown into a set of APIs for working with tabs that are independent of the specific block application. It provides many of the same API functionality as tabs module as well as some more advanced functionality.
It would be good to think through the relationship between quicktabs and tabs ahead of D7 upgrades. There's a fair bit of duplication of effort and also the potential for conflicting code and UI elements on sites running both. E.g., a "tabs" configuration menu item in tabs module sets default tab behaviour, but of course won't affect tabs created with quicktabs.
Personally I'd like to see a single API module that serves for quicktabs and other uses. I'm not sure however what the best path forward would be. What are thoughts from quicktabs maintainers?
