Feature summary (what you would like to be able to do and where):
Currently variant links id use incrementing numbers (#ca-varlang-0, #ca-varlang-1, etc.). I suggested use language name as id (#ca-varlang-zh-Hans, #ca-varlang-zh-Hant, etc.).
Benefits (why should this be implemented?):
It's easier to control individual link for JS or CSS. For example, hide specific language links.
