I am curious why Unity does not allow me to drag and drop components within a game object. It lets you move the component up and and down by one at a time but doesn’t allow you to drag and drop. Does anyone know why?
We’re working on it

Meanwhile, I would suggest XT Reorder. It’s not perfect (because some limitations of the Unity Editor) but it works and trust me, no other component reordering utility is so close to an integrated drag and drop solution.
@shawn_1 Please add the posibility to drag and drop items in a Unity events list in the inspector. At the moment you have to delete all entries to create a new order.
