Elementary OS 5.1 Hera is the successor of the Juno release with some really nice improvements, including more customization options.

However if you use it you may still wish to have even more control over it, but the good thing is that Elementary Tweaks works fine on this release, too. Here’s how to install it.

Installation

To install Elementary Tweaks on 5.1 Hera, you need to run these 3 commands after each other in Terminal:

sudo apt install software-properties-common
sudo add-apt-repository ppa:philip.scott/elementary-tweaks
sudo apt install elementary-tweaks

That’s it. You can now run it from the Applications menu.
