1) I was a bit confused initially but I think I understand, what the exclusion range does is prevent the inner coordinates from being used as coordinates. In this case, it appears to be used for both selection area and damage area. Are you referring to how they both use the same exclusion or the removal of the inner ranges? I've added a separation of this in the skill/item data configuration (1.0.2)
2) Which animation are you referring to? The selection areas for moving, selection, action, reserve? Or is it the animations for spawning, move end, action end?
They both do have a configured set of default values, the first set is configured for skill/item data if you want to specify away from default whilst the second set is configured on the battler configuration
