7 To Dos after Manjaro installation

Hi! I now have a dual boot with Manjaro and Arch and I wanted to share some recommended To dos for after you installed Manjaro:

1. Enable the firewall
2. Choose your country in the mirror list of pamac
3. Configure your update policy in pamac
4. Enable AUR in pamac if you need packages from there
5. For backups you can install and configure Deja dup
6. Configue timeshift, so if you messed up you have system snapshots to go back to
7. Optional: make your system beautiful with themes and icon sets from xfce-look.org if you chose XFCE

Which Linux distro do you use and why?
