@Kip zonder Kop : I agree with m4rw3r : Should be better to create directly a tag.
As your addon is really nice, I will see how to implement it, especially regarding the filter.
It's important to get also the lang table data when getting the prev / next article, so you just get the next article which is published (online) in the current language (article content can be offline for a given language).
Will see that as I will control all the base_model function declaration.
