Hide instrument name in galley view

I’m writing a solo piece for electric guitar so the instrument name in galley view is just a distraction and hides notes:

Is it possible to hide the instrument name in galley view?

No, it’s not possible: the instrument name is always shown as part of the margin at the left-hand side of the view.

Could you temporarily shorted the name in Setup (perhaps to one letter) to minimize the interference until you are ready to change it back to print? Since you are only dealing with one instrument, this seems one possible solution.

One instrument? Why not work in page mode!
