This problem is driving me mad.
My primary language is English, but my notes also contain a lot of German text, and plenty of stray words and terms in that language and many others. Some notes I can barely read, there's so much red underlining.
Oh, and my system setting is UK English, so it's underlining "color" and "defense" and anything ending in "-ization" etc in articles clipped from US sources.
Brand names are also getting the same treatment.
It's really stupid and incredibly annoying. And I wouldn't want/don't need a spell check even if I was working only in one version of one language.
Fix this, please!
