Really surprised by all the loose cables. That seems like a safety issue. When I was in the military, cable management was a huge thing. We would get in trouble unless every cable was secure. Having someone trip over a cable and heaven forbid break it or yank it free, could lose lives. I would imagine stakes are similarly high in space.
What you don't see on the virtual map is that the station is very much alive.
There's constantly experiments, maintenance and whatnot going on. What may look like loose cabling/equipment here and there is probably someone that was in the middle of their work and had to get out of the shot.
The more critical systems (like life support) are all behind the panels for the same reasons your realized.
It's true that you cannot trip in the narrow sense, where it is gravity that pulls you to the ground after losing your balance. While floating through the station you can however get caught by a loose cable around the ankle, experience a sudden unexpected change of direction/rotation and bump your head into a laptop/wall/ceiling/floor!
