Install Syncthing for continuous file synchronisation
Syncthing reliably synchronises files between two or more computers. Its usefulness cannot be overestimated. Add the release key with the following command:

Add the syncthing repository with the following command:
$ sudo echo "deb [signed-by=/usr/share/keyrings/syncthing-archive-keyring.gpg] https://apt.syncthing.net/ syncthing stable" | sudo tee /etc/apt/sources.list.d/syncthing.list
Install syncthing on your system with the following command:
$ sudo -- bash -c 'apt update && apt install syncthing'
Enable syncthing for the local user
$ sudo -- bash -c 'systemctl enable firstname.lastname@example.org && systemctl start email@example.com && systemctl status firstname.lastname@example.org'

Neofetch is a command-line tool that displays information about your system next to an operating system logo.

If you would like
neofetch to display every time you open a new terminal, open .bashrc with the following command:

Add the following text at the end of the file:
# use Neofetch to display information about the system if [ -f /usr/bin/neofetch ]; then clear && neofetch; fi

Hide the snap directory
snap directory in your home folder is not supposed to be accessed manually. Use the following command to hide it from view:
$ echo snap >> ~/.hidden
Hide the Desktop directory
The Desktop feature was disabled in GNOME 3.28. While this decision was not universally popular, developers pointed to the fact that, as an unmaintained feature, it stood the way of other improvements. Use the following command to hide the associated
Desktop folder from view:
$ echo Desktop >> ~/.hidden
Install Virtual Machine Manager
If you would like run virtual machines from your desktop, start with the following command:
$ grep -E --color 'svm|vmx' /proc/cpuinfo
If the output shows
vmx in red, then the virtualization extensions are enabled and you are good to go.
Proceed to install
virt-manager with the following command:
$ sudo apt-get install virt-manager libguestfs-tools python3-guestfs
With only members of the group
libvirt allowed to run
virt-manager, add the local user
bullseye to the group:
$ sudo adduser bullseye libvirt
Install Google Chrome
Google Chrome is available neither as a snap nor flatpak. This ties in with what Martin Wimpress had to say in a recent episode of the LINUX Unplugged podcast.
If, after listening to Martin, you would still like to use Google Chrome, download the official Google Chrome for Linux installer with the following command:
$ wget -P ~/Downloads --show-progress https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
Install Google Chrome with the following command:
$ sudo dpkg -i ~/Downloads/google-chrome-stable_current_amd64.deb
When you launch Google Chrome for the first time, it will ask you to:
[ ] make Google Chrome the default browser [ ] Automatically send usage statistics and crash reports to Google OK
Disable both these options. If required, you can always re-enable them later.
