Felidae is a collection of modules for Fvwm. FvwmStorage lets you define variables, load and store them from/to files, and execute any fvwm command using them. It is especially useful to interactively change the fvwm configuration. FvwmWallpaper lets you change your X wallpaper from within Fvwm. It tries to find the best way to display your picture and resizes it if necessary. FvwmXMMS lets you control XMMS by sending commands to this module. FvwmOsd lets you display an on-screen display on your X display. FvwmOsd is organized in different "channels", each of which you can configure and use independently of the others.
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.
wmsupermon is a universal monitoring dockapp. It can be used to monitor CPU usage, disk I/O, memory usage, swap, filesystems, space utilization, network traffic, wireless link quality, CPU frequency, CPU temperature, fan speed, voltages (without requiring lm_sensors), battery status (with actual, not "reported", discharge rate), traffic from your router, or anything else. It can open and maintain many dockapp windows with one dockapp process.
