Top-level fields
surface.window
Properties applied when the page pops out: a whitelisted subset of Electron window options. Every field is optional.You can’t declare the window’s relationship to the main window (it is always an independent top-level window whose visibility doesn’t follow the main window: hiding, minimizing, or closing the main window to the tray leaves it as is), its title (always
displayName), its screen position, or open and close behavior (it appears only through the file panel’s pop-out action and returns to the file panel when closed).
