i like it new style more than old one.
but menus really terrible. and not user friendly.
left side menu opening when mouse go on them. right side you must to click for open menu click close menu click open another menu click close another menu.
my suggestion is dont show any menu. when mouse go to left up side show
palette options. left down show items.
right up show ui components
right down properties.
when mouse not on the menus close them directly.
also phone image so big so you can think same thing for upper menus .this way will be more elegant and minimal design.
