Yes, I left it out since Mozart composed the "main title". Thinking
one could assume it's Mozart's cadenzas if not stated otherwise?

I'll second most of these ("introduction" was new to me tho) but
"ornamentation"? Sounds like what the interpreter does when
performing, or  maybe the editor if it's written ornaments. Maybe I'm
not getting it. Do you have an example?
