Larger better discernible designed icons perhaps sizable or in 3 different sizes and perhaps with color.

Using Sweet Home 3D in ultrahigh definition (4k UHD) on a large screen (55"), the icons are too small and quite a few unobvious in appearance. For example "create", "open" and "save" are a poor representation of their function.
