I don't object. Honestly, I don't care where it is positioned as long
it is not lifted up by the violin clef :-)
Regarding the position on a 'virtual bar line' (right before the first
note in a system): As far as I can see this is not possible currently.
While there exists a `first-note` symbol, indicating the first note in
a system, it can only be used for horizontal spacing issues and not
for vertical alignment.
No idea how difficult it would be to make `first-note` a possible
member of `break-align-symbols`.
In summary: The alignment you want needs deeper coding that I'm
capable of. Until someone is going to add that, my suggestion seems
to be an improvement.
