I'm curious about Grid too. I remember seeing some pretty screenshots back when i first started using Linux in the late 10s.
I've never put my name down for updates. But you'd expect something about progress on the site.
EDIT - i've now read: Is Zorin Grid just an old pipe dream? - #5 by AZorin
It's pretty crazy that ZorinOS is just two people. It would be nice if they had just a little more human helpers.
