The duplicate to staff above/below functions are very handy when entering orchestral music, but would be ever better if they respected octave transpositions.
This most commonly occurs when duplicating from the Cellos down into the basses. Currently after duplicating you have to then select the bass notes and transpose them down an octave. If instead when the there is an implicit octave transposition in the staff being duplicated to, such that the duplicated notes end up at the same written pitch instead of the same sounding pitch, that’d save work.
