I switched from Ubuntu 16.04 to 17.10.
Then, I found out that Workspace Grid can mimic my previous Unity 2x2 Workspace.
But there is a problem that is annoying me and I was not able to solve so far.
I start with two workspaces. To get a third one, I must have some software opened on the other two workspaces. And so on.
What I need is that my four workspaces will be always there, despite there is something opened or not.
Is there a way to this with Workspace Grid or some other extersion?
