Hi, this extension idea looks great and is something I've been looking for for a while now. None of the other "AI writing" tools seem to focus on the idea of suggesting more words as you type, which is what I'm looking for.
Are you continuing the development of the extension? I do have some ideas for additions. Although my JS is pretty basic I can probably fork and add some of them myself, and PR if that interests you.
Alternatively, if you have a reason for not developing this - perhaps you discovered some flaw in the idea, or perhaps found a different way to accomplish a goal, I'd be interested to hear that as well.
:-)
