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. -

RoundedTB
Windows taskbar customizer with rounded corners and margin controls
RoundedTB is a lightweight Windows utility focused on visually enhancing the default taskbar by applying smoother shapes and layout customizations that the native system doesn’t offer. At its core, the tool enables users to round the normally sharp corners of the taskbar, giving desktops a softer, more modern aesthetic that aligns with contemporary design trends. Beyond corner shaping, RoundedTB allows adjustment of margins and spacing, creating a floating effect or room between the taskbar and screen edges for users who want a cleaner and less cluttered workspace. 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. -

Monitorian also lets you adjust the range of brightness and contrast values for each monitor so you can set custom limits that better match your preferences.
