ModernFlyouts
Modern UI replacement for Windows flyouts with customizable features
ModernFlyouts is an open source application designed to replace the default Metro-style flyouts in Windows with a more modern, Fluent Design–based user interface. Instead of the old built-in popups for system feedback like volume, brightness, and airplane mode, ModernFlyouts temporarily intercepts those events and displays customizable flyouts that blend more seamlessly with recent Windows UI aesthetics. It extends beyond audio flyouts to cover media controls, brightness changes, airplane mode toggles, and even lock key indicators such as Caps Lock and Num Lock, offering a unified experience for all these system notifications. Users can adjust not just the look but the behavior of these flyouts (including layout, position, opacity, and animation) letting it feel more natural to individual preferences. The project’s roots trace back to AudioFlyout by ADeltaX, with further enhancements added by the community to support more flyout types and improved interaction. -
