DNSCrypt OSX Client is a user interface to conveniently start/stop dnscrypt-proxy and change DNS settings. It was specifically designed to use DNSCrypt with the OpenDNS public DNS resolvers. It includes a preference pane, a menu bar indicator, and a set of scripts for interacting with the system.
StepMenus enhances the user experience in OS X by providing a NeXTSTEP-style applicaiton menu for Cocoa applicaitons. The current application's menu is displayed in a compact floating window that can be repositioned wherever is most convenient. It is great for multi-monitor setups since you no longer have to move the cursor (and your attention) to the main monitor to access the menu for a window on your secondary display.
User Manager is a supplement to the "Accounts" pane in the Mac OS X System Preferences, designed for use with small home networks. User Manager is targeted at power users who desire full control over user and group attributes, without the need to resort to using the NetInfo Manager. With it, you can create, edit, or delete users and groups in any Open Directory node (e.g. a NetInfo domain). The interface allows you to edit nearly all record attributes, including UID, GID, login shell, and home directory. You can also manage Unix group memberships using the drag-and-drop user and group-centric interfaces.
WinSwitch is a compact replacement for Apple's Fast User Switching menu on Mac OS X 10.3 that saves menu bar space by allowing you to show an icon, custom user picture, or short username instead of the full username, while faithfully replicating and improving the other features of Apple's menu.
