I tried looking around to see if anyone else has mentioned it, so my apologies if I missed it somewhere.
I was thinking the other day how it would be nice if you could move the pet itself around in the dress up box just like you can with items when you are adding things to a pet. Say like if your'e entering it in the dress up challenge for example, or posting it to the forums. Not flip or rotate anything, perhaps only just being able to move the pet horizontally to the left or right.
There have been a few times where i would like to add in some items to the left side of the pet, but there just wasn't quite enough room there to achieve the look that was hoping for, or the things that I wanted to be visible in the background can't quite be fixed up the way that I was looking for because the pet has his head in the way or something.
