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.
