I am not at Stardock, I am a simple user.
Stardock, is in the process of developing, "start11".
It is in beta, but still paying.
I bought it and tried it: there is still work to be done, it suffers from instability.
Example, on a new installation of Win11, I put the taskbar at the top and the menu on the left. When I go up to opening the start menu, it opens, it closes and it doesn't stop!
