I discovered evilWM the other day ... I installed every WM i could find all at once and i played with them all. evil is by far the coolest one.
One thing that annoys me. You have to start programs from the command line. This isn't so bad, it just adds clutter. If anyone has ever used ratpoison, there is a feature that lets you exec a command from the window manager itself using the hotkey 'C-t !'. i think evilwm would greatly benefit from this feature. If you don't know what i mean, check out ratpoison. perhaps someone agrees with me, but if not, it's hacking time.
