pretty darn nice. i miss having pop-up folders with the control panels in OS9, so anything that lets me compact navigability in to a single dock icon is very, very welcome. it's a simple replacement for having System Preferences.app in the dock: the .app dock icon has a popup menu of the prefpanes, but only when the app is open. and since closing the window closes the app... yeah.

one request, however, is to have the option to mimic System Preferences.app by opening the "Show All" prefpanes view with a single click and control/right-clicking for the popup menu. still, though, the option to do it, as this would be a little annoying for the one-button mice among us.
