Thanks, I basically have the same view. I like i3 because it is simple and it does exactly what I want, without unnecessary animations, declarations, etc.
I was just thinking about usefull 'helper' programs people use with i3 (or other lighweight wms) e.g. dmenu, conky, feh, xscreensaver or lxappearance.
I have thought about using lxpanel or xfce4-panel with i3 but for now I do not feel the need for it.
I am looking foreward to hear what programs people use to enhance their desktop experience.
