I'd gladly bear the cross-staff were it less grand
I tried to cross-staff some notes an upper in the treble clef and the next lower in the bass clef. Apparently because these staves were not born of a "grand staff", MuseScore refused. As discussed here before, the grand staff is inadequate for organ music, where sounds on each staff might differ, change during the course of the piece, or even at the beginning, and the pedal is almost guaranteed to "sound different". So I cannot get the score to look as I want. (Of course, the boilerplate answer is, "Use the grand staff and abandon the desideratum of having it sound as you want -- MuseScore is not a performance program.") To paraphrase a famous cinematic character, "Performance program is as performance program does", and, an organist, I'd like to see better support for the King of Instruments/"Bach's Royal Instrument". Well, it doesn't even brace the grand staff correctly ...
It is amazing that the word "cross-staff" has both nautical (hence, BWV 56 title) and typography meaning.

You sound more familiar with Bach's mighty organ than I and may have exhausted all possibilities already but any chance of posting the scores (or sections thereof) - original for desired appearance and your best effort in Musescore? a)someone might have a way to do it or b)it might help developers in planning how to fix it.
FWIW, I agree it would be ncie if it were possible. Notationally, it doesn't make sense to be able to do cross-staff notation between different instruments, so I would not propose ever supporting that, but supporting different playback sounds for different staves of the same instrument might be nice someday (and different voices within a single staff as has been suggested elsewhere). But as you say, this is a playback issue, and such a feature is likely to be prioritized accordingly.
As for the bracing, can you be more specific?

That would do it (different playback sounds/"Instrument" change on different staves of the same instrument). I'd be delighted with that (the cross-staff issue would be solved corollarily). An organ is really a competing multicolor score-realizing tool, not an "instrument" with a characteristic sound.
As for the bracing, the normal bracing of organ music is to brace the top two staves; MS currently braces all three (I have seen some 19th century scores braced that way, but in the 20th and 21st century it is unheard of, even for older music).

Bracing is under your control. Just double click the brace and move the handles. But the default when adding Organ as an instrument from the Instrument list is to brace exactly as you described: top two staves braced, third staff by itself. Not sure what you are are doing that causing you to see all three braced by default?

Yup. Don't know why I thought that -- was it ever true (don't bother answering). It seems correct now as stands. Oddly, though "Pipe organ" has a 16' pedal (8va bassa) and "Organ" does not! What is the intent here?
