You could try Start11v2 which offers a full screen start menu, in the Windows 10 style ... here are a lot of customization features in Start11v2 that allow you to create just the look you want.
Thanks - I did look at this, and watched a number of videos - customisation features seemed to be more about the look, rather than basic functionality, which is why I wanted to see documentation.
Basically, I'm not after a "look" - what the desktop looks like doesn't matter, I want better grouping in project-based windows.
So I'll stick with my own version, which sort of works, but is clumsy and involves managing windows and multiple desktops in Windows 10 using vb.net software I wrotel
Thanks anyway
