Where can find lishogi.org extra piece set? Particularly is 2-Kanji set. (In Microsoft Edge)
Browser doesn't matter. You (top-right corner) >> Piece set.
@COArSe_D1RTxxx Isn't that, "Extra" mean is some browser expansion
Where do you see the word “extra”? If it's on the page, then no, it's not a browser-specific extension. Even still, I don't see “extra”, and I also use Edge.
