Yes, it's nice, as is the embedded tune player! But personally, I would appreciate also having the ABC (as at the Numachi "mirror") so one could transpose, adjust tempo, edit, add chords....

I also notice that the new dropdowns allow you to select, but not to actually go to the page referenced--at least that doesn't happen for me. In any case, I much prefer links, which I can open in new tabs (or in windows, or simply copy the link location, at MY option) without having to go away from the page I'm viewing each time I want to follow one of these references. Sometimes these "improvements" take away far more than they add.
