The binary now links Core, Gui, Quick and QuickShapes, nothing else.
Qt Widgets was there for one reason, QSystemTrayIcon, so the tray icon is gone
and QApplication is back to QGuiApplication. The cat itself is the whole
interface: right-click or long-press opens the settings window, which carries
the tricks and a quit button. Ctrl+C in the terminal works as well.
The settings window is rebuilt from Qt Quick primitives. AppButton, AppSlider,
AppToggle and SettingsGroup replace the Controls types, keyboard handling and
accessible roles included, and a Flickable with plain positioners replaces
QtQuick.Layouts.
