Dark page and dynamics
View → Dark Interface switches the window’s own colours between dark (the default) and light.
View → Dark Page shows light notation on a dark page, which is easier on the eyes at night. It changes only the screen: a PDF is always printed on a light page. The area around the page stays dark either way. OxiGuitar remembers these choices, and the rest of the View menu, the next time it starts.
View → Dynamics shows or hides dynamics markings such as mf and pp (hidden by default, as they clutter the page; Mateus, 20 Oct 2026). Guitar Pro 3 to 5 files store loudness per note rather than as markings, so they never show any.
