Just a warning: The current version has performance issues, it stutters like crazy even on beefy setups. It seems they didn’t get the level streaming implementation of UE5 right on the first try. This will probably get fixed for 1.0, but currently it’s painful playing in some parts of the map.
It is not as complicated as it looks! As a long time windows user I’m in the process of getting used to the command line and I love the simplicity and direct way of doing things.

For other stuff like visualizing a directory tree you can always use a mouse interface. You’re rarely forced to use the terminal.
