* **File manager:** Install `nautilus` (not adaptive yet). Download [this ](https://source.puri.sm/Librem5/phoc/-/blob/master/helpers/scale-to-fit) and scale it to fit the screen. From the directory where the script is run `scale-to-fit org.gnome.nautilus on`
Note: Exercise caution when downloading files from the internet.
File manager 'nemo' scales well without additional tweaks, especially in landscape.
* **Firewall:** To enable ufw (uncomplicated firewall), open terminal and enter `sudo ufw status` and if it's not yet enabled, enter `sudo ufw enable`. The default is usually all you need, but you have the options of adding additional rules. To call up a graphical interface inside the terminal, first install gufw and install x11-xserver-utils. Next type the following command: `DISPLAY=:0 xhost +` and hit enter, resulting in: `access control disabled, clients can connect from any host`. Now type: `DISPLAY=:0 GDK_BACKEND=x11 sudo gufw` and the graphical version will appear right in the terminal. (Note that after you close the terminal, the app icon in the phone's app list will not be operational unless you repeat the above process, at least unless someone adapts it later.)

* **Install Software:** In case installing software from PureOS store does not work --> Do it from terminal e.g. `sudo apt install firefox-esr` and `firefox-esr-mobile-config` (for better screen fit). Note that PureOS store, by default, lists software that has been adapted to the Librem 5's screen. Other packages can be found and installed using the search tool within the store, but may not scale well to the screen without further modification.
* **Root account:** Locked by default. So there is no root password available. More technical details [here](https://source.puri.sm/Librem5/image-builder/-/merge_requests/123). Unlock root account with `sudo passwd`, check out [this discussion](https://forums.puri.sm/t/what-does-locking-the-root-password-do/10895) for more background.
* **Screenshots:** Install `librem5-goodies`. After install it will show in the app tray as: `Screen Shot`
