I’ve noticed that working in Galley View with “Single Players” holding different instruments, it gets confusing to see what staff belongs to which player.
Here is a suggestion… Perhaps a gray bar (same color as the names) that joins the instruments the player is playing together, so you can see easily who owns what? Created far enough into the write area that it is easy to see. I created a mock up below.
On Mac I Command-Shift-click a link to load in a new tab. I do that with the list of threads too. On iOS, press & hold on a link to get the choice to load in a new tab
