Quote - I'll give you a recent pet peeve of mine...mat pose files for characters or hair that include x, y or z trans for various parts of the body, etc.

I'll give you another one.  Pose files that move the body for no good reason.  It's one thing if it's one pose in a set meant for characters (say a dancing couple).  It's another if it's a pose for a single character.  I have a large scene, I move the figure where I want it, carefully making sure the feet touch the floor and so on, look at it, decide a slightly different pose would be better, click on it and the figure is back at the origin.
