I think I brought this up before but now I have fully thought this through. Large groups (e.g. strings) will be grouped with thick brackets. They have an extra amount of space between each other and can optional go under one name. Small groups (e.g. violins) will be indicated with thin brackets or braces. You can have a groupwide name (e.g. Vln.) and and assign group names (e.g. II). They still retain their own names though, so if the play alone it will show Vlns. II not II. There could be an option to display system text above certain large groups in addition to the top instrument.
