Add-on ToggleME Xenforo Language support


I was testing the Plugin ToggleME from @cclaerhout and it is actually working fine.
My Problem is that the language detection of the Browser is not accurate enough for me :confused:
On mobile phones I get the english Toggle settings even if I would expect to get the German onces.

So please could anybody implement a Language switch dependent on the Xenforo Language the forum user selects?

This would be the logical solution for me and the most accurate one.
If I am a German speaking person and select German as Forum Language, why should then ToggleME switch the layout to the english layout.

I was asking cclaerhout if he could do the implementation, but he sayed he will not implement new features and that I should implement it as it is opensource.

But I am not good with PHP and Xenforo :(

So maybe someone finds this feature useful and implements the Language Switch dependent on the Xenforo Language and not only on the browser detection.
