Hi,
is it possible to add "double wiki extension" in Wikipedia sites (en.wiki,...)?
it will be useful for comparing also translations between two wikis contents.

It would be possible, but you need local site consensus to enable this

why consensus?
it can be like gadget and who want have this possibility activate js code that shows <=> icon in pages.

Hi,
we had consensus and common accepted to Enable DoubleWiki extension on fa.Wikipedia
