XenInfo gives widgets info such as battery, music and weather. You MUST have legacy disabled in XenHTML for XenInfo to work with that widget.
XenInfo works with XenHTML and widgets coded for XenInfo you can find these widgets in the XenHTML section of my repo.
There is no weather app on the iPad so you must have the weather widget in the Notification Center or wherever widgets are displayed on your firmware. You must allow this widget to load at least once. Location services needs to have weather enabled always. If you get a popup asking allow on springboard click yes.
