Ubuntu 20.04 - Gnome behaving like Unity aka "Saving private screen space"

gnome-unity.sh

#!/bin/bash

# Upgrading from Ubuntu 16.04 to 18.04/20.04 you quickly realize that Gnome didn't really
# got better for the past 10 years. Yep Gnome 3 got released in 2011.
# The amount of screen space wasted is so real. Multi-monitor is so bad.

# Install and tweak extensions to behave like Unity, which had:
# (1) consistent UI
# (2) multi-monitor management
# (3) stable code

# This should be default packages
sudo apt install gnome-tweaks
sudo apt install gnome-shell-extensions

# Packing web browser extensions with external APT dependencies (-_-'), required for Firefox too
# You will get a cryptic error otherwise:
