If you copy the Chrome Bookmarks file into the Opera 22 profile (replacing the Bookmarks file that is there), they should show up instantly. Or at least, that's what people have reported in the forum.
I don't follow the alternate way you're suggesting, dejonn, though it seems more complicated. You seem to be saying you need to make the Chrome bookmarks into an html file, and drag and drop that file into the address window of Opera, and ???? What do you mean by the quick launch bar? And what icon will open your bookmarks?
Just copy the Chrome bookmarks file into the Opera profile (replacing the bookmarks file that is there).
