Every popup is now called *Popup instead of *Window in its file, root node, node name, class and variable, and PopupWindow becomes BasePopup. Player is PlayerRow, SongListObject is SongRow and Character is CharacterCard. Script files are snake_case and scene files PascalCase, each matching its class or root node, and LightGrayTheme.tres is light_gray_theme.tres.
