In case you find it at all useful:

Make iTunes Music Store arrows search within your library, rather than going out to iTMS:

defaults write com.apple.iTunes invertStoreLinks -bool true

Allow Dashboard Widgets to be dragged away from the Dashboard and onto the ‘normal’ layer you work on:

defaults write com.apple.dashboard devmode -bool true

A different progress indicator in Safari 3:

defaults write com.apple.Safari DebugUsePieProgressIndicator -bool true

Safari debug menu:

defaults write com.apple.safari IncludeDebugMenu -bool true

Safari Web Inspector - not as good as Firebug, but pretty good:

defaults write com.apple.Safari WebKitDeveloperExtras -bool true
