I think it would be better if in the Outline screen I don’t need to select Game Object and then use right mouse button to go to Add Component. A better way, I think, could be if I just use the right mouse button in a open space inside the Outline screen, because when I use add component the new component created is automactally selected, and it very good, but if it’s need to add another component I need to select Game Object and use right mouse button and so on…
Less clicks, better process. - Right… this was fun
