There were also debates on whether the developer should rework on the GUI, and even this guy propose for new GUI, turned out that things are not so simple that in up until now the guy in Blender tend to keep the GUI as it is now. After watching the video (on his new GUI propose along the difficulties of implementations), i kinda have better understanding that Michael must had very deep considerations on MoI interface, on how each function should work, resulting efficient and friendly GUI as we all know.
