First of all, thanks for this great plugin. I'm using it with my en/es website and it's working perfectly, but there's a thing I'd like to change. Right now the flags are showing in the header of my website (cause I added the function you said in the wiki in the header.php of my theme) but I would like it to appear in my navigation menu instead. I saw the "Manipulate the Navigation Menu" part in the same wiki but I still don't understand where I would have to add this code.
I know this could be a super dumb question, but I'm new at this.
Thanks in advance.
