First thing, it is selective (you can turn it off or on) and second, it should translate all internal links, unless those are generated by javascript or another dynamic client side method, other cases are solvable, I would appreciate any link to places where the links are broken (eg. on this link – look at this..) and would try to fix them
Kitu kwanza, ni kuchagua (unaweza kugeuka kuwa mbali au) na ya pili, ni lazima kutafsiri viungo yote ya ndani, isipokuwa wale ni yanayotokana na javascript au nyingine nguvu mteja mbinu upande, kesi nyingine ni solvable, Ningependa kufahamu uhusiano wowote na mahali ambapo viungo ni kuvunjwa (km. kwenye link hii – kuangalia hii ..) na ingekuwa kujaribu kurekebisha yao
