OK, after getting a bit frustrated with this, I finally found out how to add virtual workspaces to Antergos MATE. Like most things, it’s easy once you know the trick.
With the latest version of Antergos/MATE, do the following to enable workspaces:
- RIGHT-CLICK on the panel
- Select Add to Panel
- Search for “Workspace”
- Select “Workspace Switcher”
This will create the workspace switcher applet on the panel which you can configure to your hearts delight.
I must be one of the few people that use this feature, judging from the paucity on information about it.
