Proposal: Improve handling of transposing instruments in the Score Wizard about frescobaldi HOT 2 CLOSED

In my own scores, I usually rewrite guitar and bass part definitions like so:

electricBass = \relative c, {
  \global
  % Music follows here.
  ...
}

electricBassPart = \new Staff \with {
  midiInstrument = "electric bass (finger)"
  instrumentName = "Electric bass"
  shortInstrumentName = "E.Bs."
} {
  \clef bass
  \transposition c
  \transpose c, c \electricBass
}

The double transposition is clumsy, but saves me having to change every relative octave in complex existing scores. For the Score Wizard it would make more sense to just use \transposition c and change the initial \relative pitch for the music block.

For transposing brass and woodwinds, I actually create two versions of each part. The first is displayed at concert pitch for my working score; the second is transposed to the appropriate written pitch for publication.

scoreATrumpetBb = \relative c'' {
  \global
  % No \transposition command here; put it in the part definition as needed.
  % Music follows here.
  ...
}

% Displayed at concert pitch
% This goes in the main \score block
scoreATrumpetBbPart = \new Staff \with {
  instrumentName = "Trumpet in Bb"
  shortInstrumentName = "Tr.Bb."
  midiInstrument = "trumpet"
} { <>^"Concert pitch" \scoreATrumpetBb }

% Displayed at written pitch
% This goes in a separate \book for the individual part
scoreATrumpetBbPartTransposed = \new Staff \with {
  instrumentName = "Trumpet in Bb"
  shortInstrumentName = "Tr.Bb."
  midiInstrument = "trumpet"
} \transpose bf, c { \transposition bf \scoreATrumpetBb }

Granted, I'm not looking to make the Score Wizard go that far -- I realize mine is a somewhat unconventional approach. I'm just mentioning it to contrast my own use case with the one the Wizard currently assumes. Being able to generate the transposed version automatically would be a considerable time saver for me; the rest is personal preference, and I'm fine doing that manually.

I'm closing this issue because I think I've got the Score Wizard behaving sensibly now, and since no one's reverted those commits yet I'm presuming others agree. :) Probably better not to overcomplicate things at this point. Thanks all, especially @jeanas, for your help and patience on this.
