The appinfo:/ KIO slave combines an application's configuration, data, manual and temp files and folders into a single view.
This version is a prototype (i.e. the result of two evenings' work). If you think it's a good idea let me know and I can work on implementing some of the features properly. I also welcome feature suggestions and any other feedback.

Just type 'appinfo:/' followed by the application name you're interested in the konqueror address bar. Typing 'appinfo:/' will list all the applications found in your $PATH.
