Bilingual Spell Checker

Nowadays it is very common to use at least two languages in our work environment, especially in writing. Concepts and research – a lot of things are done in our own language, but a significant amount of information and terminology is often in English, as the language is universal and therefore an enormous amount of information material is available online in this way.

It would be enormously helpful if the spell checker could work for two languages at the same time, for example German AND English in my case. At the moment I have to use either one or the other and this almost always leaves me with too much text that can't be checked directly, and of course with a lot of red underlined words.

Thanks!
