Thanks! I'm the king of backup, but I wouldn't want to backup everything each time I flash something if I'm going to format. I just backed up last night because I made another nandroid before trying that theme one more time.
One of these days I'm going to experiment more with restoration. I noticed in recovery mode that when you select "backup" it backs up everything in the nandroid folder. Otherwise, you also have selections to restore individual portions of the nandroid (i.e. data, apps, etc.), so I'm assuming that theoretically you could restore a ROM, and then choose another section of another ROM and restore that to the current build. Make sense? Just wondering. It's a slow day at the office.
I'm sure there are limitations involving mixing data from two separate builds, but it's just a thought. I haven't looked inside a ROM to see what's there.....yet.
