Hi, i tried dwm for the first time a few days ago, after years of using wmii. my impression was, that it is much more simpler than wmii. but something i missed where clickable buttons in the status bar, and so i started to play a little bit with the code.
The result is an statusbar, where the stdin is splitted by "|" to several buttons, for each button actions can be defined. It looks like this: http://img161.imageshack.us/img161/115/200703042014361024x768ssk9.png i attached an diff of the actual mercurial version didi
