The actual model selection is something i can define as being annoying, just because it has no reference to which model are you actually moving or aiming at, but only has its own XYZ gizmo like some sort of guide to show you what are you manipulating, but still something odd to be honest.
It can be just a single color around the entire item, and this way we can afford to view it clearly among other models, these which are probably between a whole map scenery filled with lots of things around.
