Inspired by wmutils I'm working on some window management utilities that operate on EWMH, I call them ewmhutils. They are a collection of scripts that use wmctrl(1) and xprop(1) to do some EWMH manipulations, such as pcd(1): print current desktop/workspace number, ndesks(1): print number of desktops, wstat(1): print window state (whether it is hidden, maximized, fullscreen, etc).

I'll probably convert those scripts to C.
I have already converted to C the one that change workspace focus, because the script was too slow. I'll probably post it in github soon.

I'm also working on changemon(1), a wm-agnostic utility that uses Xinerama to change the focused monitor.
For example:


And also, I'm working on shod(1), my EWMH-compliant window manager.
shod(1) is the project I'm less proud of, because of the number of bugs it has. I use shod as my daily wm, however.
