DSWM (Deep Space Window Manager) is a tiling keyboard-driven X11 window manager. It is based on StumpWM code and is written entirely in Common Lisp and oriented for good usability with minimum startup configuration and good integration with Emacs. The project is under hard development, so it has many experimental features.
feed2wmmenu is a tool to generate X11 window manager menus from RSS, ATOM, or other news feeds. It was inspired by "fvwm-menu-headlines", which generates static refreshed FVWM menus from RSS or other kinds of news feeds. The drawback of the FVWM related script is the use of simple regular expressions. feed2wmmenu polls the feeds using curl, utilizing the Last-Modified header so that the feeds are potentially not fetched if they didn't change since the last poll. It produces diverse output formats by using corresponding XSLT stylesheets.
Notion is a tiling tabbed window manager for X. This means the screen can be freely divided into tiles that contain the client windows. Multiple client windows can occupy the same tile; in that case they will be tabbed, much like browser tabs. This way, windows will not overlap and it becomes easier to manage your screen real estate. Its functionality can be configured and even extended with Lua scripts. Various scripts are available, such as for NetWM features and multihead support.
