    KeePass

    KeePass

    A lightweight and easy-to-use password manager

    KeePass Password Safe is a free, open source, lightweight, and easy-to-use password manager for Windows, Linux and Mac OS X, with ports for Android, iPhone/iPad and other mobile devices. With so many passwords to remember and the need to vary passwords to protect your valuable data, it’s nice to have KeePass to manage your passwords in a secure way. KeePass puts all your passwords in a highly encrypted database and locks them with one master key or a key file. As a result, you only have to remember one single master password or select the key file to unlock the whole database. And the databases are encrypted using the best and most secure encryption algorithms currently known, AES and Twofish. See our features page for details.

Along the monitor state and setup the resolution is also saved and restored. The program works by saving a current monitor setup as configured using the windows control panel to an xml file. Once saved the configuration can be quickly restored at any time. Requires .NET 4.0 Framework to be installed. The program is quite simple and in an early development stage. It is provided without any warranty. If you accidentally disable all your monitors boot into safe mode to fix the problem.

    RoundedTB

    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.

    ModernFlyouts

    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.

    Monitorian

    Monitorian

    A Windows tool to easily adjust brightness of multiple monitors

    Monitorian is a desktop utility designed for Windows that gives users a simple and centralized way to control the brightness (and optionally contrast) of multiple displays from one place. It supports both built-in laptop screens and external monitors, allowing adjustments either on a per-monitor basis or all together at once, making it especially useful for multi-monitor setups. The app displays sliders for each connected monitor, and on systems with ambient light sensors it can show both the configured brightness and the sensor-adjusted brightness to help you fine-tune lighting according to your environment. 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. Usability features include gesture support on precision touchpads and easy renaming of monitors to keep them organized in the UI. Its interface sits in the system tray for quick access.
