The aim of LucED is to be a fast and responsive X11 text editor with a simple but powerful user interface similar to NEdit. It uses Lua as an embedded scripting language, and features syntax highlighting that is configurable via PCRE regular expressions with arbitrarily nested patterns.
libNUI is a hardware accelerated GUI framework that makes it possible to build rich multi-platform applications based on 3D rendered dynamic layouts. Interfaces are built as a composition of widgets and behaviors, and the framework handles positioning, resizing, anchoring, and texture stretching. Objects are connected with synchronous events and delegates for mono-threaded communication, or asynchronous notifications and message queues are used for multi-threaded applications. It also supports strings (including Unicode), paths, files, data streams, fonts, threads, critical sections, audio buffer rendering, and more.
dualscreen-mouse-utils is a set of two useful utilities for dual screen setups (e.g. :0.0 and :0.1). mouse-switchscreen switches the cursor between X screens and remembers the last used position. mouse-wrapscreen wraps the mouse cursor from one screen to the other on the specified edge, even when the screens are configured to be apart and would normally be uncrossable.
QuickTile is a simple attempt to duplicate the basic functionality of WinSplit Revolution for users who don't like the Compiz Grid plugin. It should work on any X11 desktop with PyGTK 2.2+, a window manager that supports the modern range of NETWM hints, and (if you want internal keybinding) python-xlib.
XDRadio is a simple to use XDialog wrapper for radio listening, It use MPlayer for radio listening and v4l2-cfg for mono-stereo shifting. It will hopefully run on any X Window system. XDRadio is intended for desktop end users with a radio card in their personal computers. It comes in 2 localized versions: French and English. The initial setup is easy, and explained in the README and with comments in the files. After this setup, you will be able to easily control your radio card.
xsettingsd is a daemon that implements the XSETTINGS specification. It is intended to be small, fast, and minimally dependent on other libraries. It can serve as an alternative to gnome-settings-daemon for users who are not using the GNOME desktop environment but who still run GTK+ applications and want to configure things such as themes, font antialiasing/hinting, and UI sound effects.
x9wm is a clone or fork of the 9wm and w9wm X window managers. It is a light alternative for the Mac OS X desktop. All of its source code is contained in a single file. It supports an alterate red colored cursor. It is very light on resources, quite fast, very simple, and easy for long programming, editing, or Web work sessions. You can blend it with Nitrogen and Wbar to create a simple but elegant interface without iconic or stylistic clutter. It does not decorate windows with borders, and it is modal, controlled with the mouse.
