I recently upgraded from 14.04 LTS to 18.04 LTS Bionic Beaver and I really miss the old, simpler workspace switcher. The 4-way quadrant icon in the Task bar was much easier for me to use and think about, better (for me) than the new Activities -> vertical column of workspaces.
Is there a way to get the old Unity workspace switcher back? I was delighted to find Nemo, which solved my issues with the new Gnome File Manager (versus the old Nautilus in 14.04). I'm hoping there's a similar solution for the workspace switcher too.
