The biggest new feature in Archinstall 3.0 is a revamped text-mode user interface (TUI) that now uses the Curses terminal control library, which allows for more complex layouts and a new but familiar look and feel of the menu-based interface.
As you can see from the screenshot above, the new Curses-based interface now opens each main setting of the installer in a side panel rather than a separate page from the user needs to navigate back to the main menu. This should make the installation a lot easier for Arch Linux newcomers.
