Also, MoI's UI look and feel and colors are "TOTALLY CUSTOMIZABLE"! A great acheivment by the design.

While in its beta state you havnt seen the iterations of "Skins" but they have been done. When it's released maybe a few more will pop up that you like the look of.

I've seen "Pilou" show some different looks. Maybe he can demonstrate here now?

As far as the look I dont think you have to worry. Custom UI is a HUGE plus with MoI! You can even create your own graphics and replace, to make your own "buttons" "tabs" "text" and whatever. Most apps let you choose "Colors". MoI, far superior here :O
