PowerShell ISE Addon: Reset all ISE preferences

Ever since PowerShell v3.0 CTP build got released, I am using ISE as my primary script editor. I keep changing preferences such as colors, etc. The new feature in ISE v3 remembers the changes made to ISE options. While this is quite useful, sometimes resetting all the changes we did can become painful. I need to use Tool->Options dialog and then click the 'Restore Defaults' button Or we can use the $psise.Options.RestoreDefaults() method. I am not sure of any other method unless I missed it in the RTFM
