Lunchbox is a dynamic tiling window manager for X11. It allows windows to be resized by squishing them against the edge of the screen. In a step away from the desktop metaphor, all programs are given a separate workspace and unique arrangement of windows, and any window can become the desktop. It offers an in-built scalable tab replacement called the Title Menu, which allows any window to be swapped with any other window that fits, allowing very fine grained control over the layout of the screen. Finally, although many windows default to tiling, any window can be changed to a Floating mode, which dialog boxes default to.
euclid-wm is a minimalist tiling window manager for X11. It is designed to allow quick and easy management of numerous windows entirely from easy-to-learn, Vim-like key-bindings. It seeks to do two things in particular: balance the ease of use common among automatic-layout tiling window managers with the flexibility of manual layout window managers, and create a useful way to handle minimized applications.
Xacpimon is a simple battery life indicator for Linux notebooks that support ACPI power management. On notebooks that use X Window System displays, xacpimon displays a basic progress bar that indicates the percentage of battery charge remaining. The program runs in any X Window System environment and is designed to be flexible enough to handle various notebook power management configurations.
Showkeys is a simple program to display keys being pressed on the screen. It is useful while making presentations and screencasts. The audience will be able to see the keys being pressed. It is similar to key-mon. Key-mon has more features than showkeys. but the latter solves some specific problems: it doesn't use GTK/GNOME; uses libxosd to display keys directly onto the screen; has no floating windows to that always need to be on top (which is very useful if you're using a tiling WM like Xmonad); and has keystroke history. key-mon has keystroke history, but doesn't show modifiers. showkeys does, using an Emacs style key notation.
