I'm using the excellent translation plugin on this testing site
http://01010.org/textbook/ Notice the hardcoded navigation links at the top which always leads to the English version of that section/namespace.
It would be brilliant if I was in say, a French article or contents page, and could click on Reference in the nav bar and be taken to fr/reference instead of the English version. Is there any possibility of making this happen? Unfortunately, I don't know any php or I'd have a go myself, cos I'm figuring it won't be much different than getting all those admin buttons to change language.
BTW, I also want to say I think Dokuwiki is great and it didn't take me long to bash it into the shape I wanted. The translation plugin really tops it off for the site I'm working on there, makes it very intuitive. Great work!
