As we all know, Windows has added acrylic blur to menu bar menu/context menu for many years, and Rhino has been using Windows Classic style of WPF, or Win32 C++ default style. In Rhino8, the color is customized to adapt to dark mode.
In order to make Rhino UI more modern, it is necessary to match the background material of Rhino menu to acrylic blur.
In addition, modifying the menu option height and margin details to match the latest Windows design specifications (WinUI2.6+ is used as the standard here) will make it more perfect.
