Quicktabs Panels Integration

Provides a CTools/Panels' content type plug-in for Quicktabs blocks. Can optionally provide arguments/contexts from the Panel to those Quicktab tabs which are Views type. Requires views_content module which is included in CTools.

If you enable this module after having already included Quicktabs blocks (via the Miscellaneous option) in your variant, it will probably still work (?) but you won't be able to edit it. But you ought to be able to re-create it fairly easily. I'm curious to learn what happens, in any case.
