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.

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.

This flexibility extends to segmenting the taskbar into distinct areas or profiles, which can help with organization and visual hierarchy across different workflows. The application integrates with Windows 10 and Windows 11’s taskbar behaviors without modifying core system files, ensuring stability and preserving native functionality while still offering powerful personalization. -
