Recognise LanguageTool Spell Checker in SW main editor -- quick fix

It’s hard to believe that a story processor that is as good as SudoWrite does not have even a rudimentary spell checker! WTF?

I have the Language Tool spell/grammar checker (free version) extension for my browser (Firefox) which works just fine for _everything_except_ the SudoWrite main editor for some strange reason. (It’s even working here in this reply box.)

Why not in the SW editor? That could be a quick fix !!
