Adding functionality to translation tab on mod page

[Hilli1]

I have a suggestion. I offer all my mods in three languages. I write it in the brief description and I tag the mods accordingly. I talked with some people and realized that many people just looking for a translation tab and move on if there is none. However the a translation tab only appears when there is a different translation page. So my request is, that a mod author should be able to manually add the translation tab and then can choose which translations are available on his page. The previous functionality should remain unaffected.
