Now you can walk on your ship... And others, too
The window where you can see your ship became smaller,
so now you have to walk around it
in order to see the whole picture.
To do this, use WASD keys (I'm assuming you're using desktop computer, not a mobile phone).
If they don't work - focus the webpage, check your keyboard language and state of CapsLock key.
Also, now you can check what's in those cargo containers all over your ship. Moreover, you can dock to other ships, and explore their containers, too! To undock from a ship, use "Undock" button available when you're in Airlock. You'll be automatically docked to a new random ship in 5 seconds.
