QDS is a library for Qt developers which provides cross-platform access to additional features of the various desktop APIs. The main goal is to require only minor changes to Qt applications by providing alternative implementations of Qt classes where possible. An application using QDS does not have compile-time dependencies on the desktop APIs and no run-time dependencies on the Unix and Linux desktop APIs.
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.
Univert is a Universal Unicode Converter, at least as universal as the Unicode implementation in Tcl 8.1 or later can manage on your computer. Univert will convert interchangably between the following formats: native Tcl unicode, hex bytes or words separated by spaces, decimal bytes or words separated by spaces, HTML entities, UTF-8/URL encoding, quoted printable with whatever the current encoding is, and C string with whatever the current encoding is.
