That's a completely useless comment, you'll have to explain what you don't like about it
If I may articulate, it's much easier and more natural to look over and see the color of the model and look at the UI than have to focus on what the model is doing at the time.
Plus, the shape of the new duplicator, which is very different from the traditional wand-like tools, is out of place. It's easier to notice the color of the wand and know exactly what it is rather than have to think whether or not it is a tool for building.
It's just out of place. When the points and purposes of a duplicator (or any building tool) are speed, efficiency, ease of use, and flexibility, these superfluous models prove to be counterintuitive.
P.S. — Please don't pull the "your opinion is different from mine, and therefore invalid unless an brown townysis is written for your case" card. It just makes you look like an ass.
