I see they have a workspaces applet that has "row" and "column" in the source code. I'd love to see a GNOME-like DE that supports 2D workspaces again so I can happily abandon my GNOME extension (Workspace Matrix). I couldn't figure out how to run COSMIC so I couldn't test if the applet really supports 2D workspaces, though.
