Hi feirui445,

re:
> could you consider designing a new UI to enhance the competitiveness of this product

There is a new "Dark Mode" UI available in version 5, you can turn it on under Options > General > "UI Theme: Dark".

See here for some discussion of some of the problems with that particular graphic design example that you link to:
https://moi3d.com/forum/index.php?webtag=MOI&msg=11158.2

Just purely cosmetic graphic design "looking cool" is a very low priority for MoI compared to actual workflow UX design.

I'm definitely not interested in losing actual usability just for a cool look.
