Regarding opera sub/sur-titles:
Out here in Santa Fe the 'new' opera house this year will feature an
electronic libretto on the back of the seat in front of you. I'm pretty
sure you can turn it off if you don't want it.
I don't know but the propaganda claims its the 2nd one like it in the
country, after the Met??? IIRC.
Food for thought.
