A tab defines a
labeland, optionally, anid; thelabelis used as a fallback forid. The mechanics in the background is simple: the site maintains a priority list for a user and shows the tab with the highest priority (or the first tab if no language appears in the priority list). Choosing a tab simply bumps the language's priority.These tabs can also be used for arbitrary other content. At least technically. :)
