I think it would be a good idea to have the option to avoid automatic secondary brackets for Violins 1 and 2. This is an especial case in the orchestra… The problem arises when divisi is added:
(The problem is worse if labels for the divisi are removed).
I know that this can be changed manually, but if divisis are changing constantly it gets quite laborious…
Another possibility would be the option to automatically add sub-sub-brackets to the divisi.
