What's funny about this is that I and many others use Classic Shell to get exactly this "multi-level start menu from hell" back in Windows 10.

On Linux I only use Desktop and Window Managers that I can configure relatively freely and easily. No need to patronize users.

Old school Windows start menu was a great menu. It was just a menuized folder hierarchy, simple and effective. The only real flaw was that you only had one, you couldn't add new "start" buttons pointed to different folders for custom menus.

At some point they added the ability to kinda do that, (right-click taskbar -> new toolbar...), which still works on Windows 10.
