Maybe it's just me, but this PrefPane doesn't do anything. I mean, it has every widget listed, and they are all checked--even though I'm only using a few of them. Whether I check/uncheck one, my Dashboard doesn't change--despite reloading each time I check/uncheck a widget.
I can see a benefit to this Pane, but it doesn't work.
One question though: Exactly how should multiple occurrences of a Widget be handled by this app. Weather, RSS, Clock, and Package Tracking widgets can easily have 2 or 3 instances.
