Brave spellchecker

I would like to see full US English (with ALL modern colloquialisms) implemented in the English distributed Brave copies. The “checker” is NEVER EVEN CLOSE to correct, even when it’s SEVERELY obvious. It’s quite obvious this is done “overseas”, and isn’t helping ANYONE who wish to improve themselves or others. I read Tolkien in ORIGINAL olde english, REQUIRED, in high school for lit classes. And THEN, was coding on a DEC VAX 1178 by '76…
Please look into this.
