When selecting the mode for diffs there is a name that pops up, that name is the technical name given to the differential. I t would be much cleaner if the uiName name was given instead since it can be clearer what diff part it is. Example below: ["differential", "differential_R_1", "driveshaft_RR", 1, {"diffType":["open","locked"], "lockTorque":5000000, "friction":8, "uiName":"Rear Differential"}], differential_R_1, is the name that shows up when mouse is hovered over the diff (in picture) Rear Differential is the name that should show because its cleaner
