add solo to the normal(section), pizzicato, tremolo options
Pretty much what the title says. Also, add options for clarinets to switch to Eb, A/Bb, or Bass, flutes to piccolos, oboes to English horns, bassoons to Contras. With transposition changes at that point in the score.
And not with the instrument change text either - that makes your mixer/instument list really huge really fast.
