I enjoy organizing sheets with the grids produced by the Master Layout Settings dialog box.
However, I don't actually want them to print.
And I don't enjoy having to toggle them on and off in each master to keep them from printing.
One solution would be to add a Print Grid checkbox in the settings dialog as shown in the attached image.
If it was checked by default, then I assume it would not cause issues for current users if it suddenly appeared in the next AC10 update.
