-Stop Quicktime and Preview from Auto-Restoring What You Left Open

Auto-restore is a handy setting that opens up your last used file in your apps. That's fine for most apps, but it could potentially lead to some embarrassing things in an app like Quicktime or Preview. Thankfully, it's easy to disable that feature on an app-by-app basis: For Preview: defaults write com.apple.Preview NSQuitAlwaysKeepsWindows -bool false For Quicktime: defaults write com.apple.QuickTimePlayerX NSQuitAlwaysKeepsWindows -bool false
