Ubuntu 20.04: move window buttons to left / right

Problem

You want to move the window buttons (e.g. Close) to the left / right. How to do that?

Solution

I found a short video about it here (length: 45 sec).

To sum up: launch the app Tweaks, then Window Titlebars -> Placement.

[manjaro] change window buttons layout

Problem
On my desktop I have a Manjaro that I installed years ago. It’s a rolling release distro, meaning I get all the updates, but the graphical interface is not always updated. For instance, I installed a new Manjaro on a laptop, and Manjaro looks much better on my laptop than on my old desktop.
On a newly installed Manjaro, the window buttons are on the right side, but on my desktop they are on the left. How could I unify them and move the buttons to the right?

Solution
I found the solution in this video: https://www.youtube.com/watch?v=yVfHDyWcgSA . In short: start the Settings Editor, select xfwm4 on the left, edit “button layout”, and provide the string “O|SHMC” (without quotes).
