Have not given much thought on this. And it might turn out to be a worse
solution than the current one. But I firmly believe that the macos solution
can be improved. but it was the right decision to go to it instead of the
space killing NextStep menu.

Well. I have one idea. Some arrows at the end would give you scrolling
access to what is
not seen. Might have some ctrl+drag behaviour as an alternative for the more
experienced.
The focused application would of course have the prominent position. Ether
it's the first or
the middle position. The ordering of menus around it are not based on uptime
of the application
but rather on when it last had focus. Basically working in a similar fashion
as the alt+tab
application switcher where a single tap gives you the last application used
and then the next
latest application. The location of these menus based on that information
would then be
ordered around the focus application menu.

See above. :)

This is true for the focused application. Accessing other application would
be simpler
and quicker. For people that often work in multiple application at a time
this could be
revolutionary.
