I am checking Softmaker Office as a replacement for ms office in Linux. My work requires multilingual documents (technical reports etc.) which contain different language even in the same sentence. In Linux, the spellcheck language does not automatically change, when I change keyboard language/layout...

I have installed FreeOffice as well as the Trial version of Office NX.
It's 4 years since the original post, albeit, I find that language detection is still missing... Is that true or am I missing some setting?
