This idea does not belong to me. I quoted from an interview recently given by Gary, the designer of the UI-design interface at Rigo Design:
For designers, it is very important to solve specific user issue. When we are talking about MIUI 8 it was a really hard work to create a superb user interface which will be brighter and more interactive than ever. It includes an internal optimization in accordance with innovation MIUI style of Xiaomi. The great example of this is an animation of shredding paper. It’s about Notes application which liked most of our co-workers. If we compare MIUI 9 and MIUI 8 you may find out that there aren’t any strong differences. The main answer is that beautiful design is long-lasting. Changing for the sake of change is not a good idea. The exception is when you made mistakes from the start.
Smart design is evolving. Some designers are conservative. Others prefer to be innovative. They are open to the new user requirements. I prefer innovative designers. If they are futurists is formidable. I like to think I’m still able to adapt quickly to a new design. At first it will be harder for me to get used to, but I will finally succeed. It’s a challenge.
