johnnylighton,
Couldn't agree with you more, regarding Nova's power.
Regarding the TW setup:
I first install Nova on my S2, right after ICS upgrade. Cost me lots of restoring. So before I set up Nova Prime on my new S3 and Note 2, I got the "Desk Migrate" app, which copy entire TW icons, shortcuts and widgets, as well as I did backups of widgets themselves, along with Nova backup. The restoring on brand new device, took literally less than 3 min.
Many of these backups are stored in DATA folder, or corresponding widget folders, which I just copy paste from one phone to another.
