I personally like the looting aspect. I do agree that there should be a sense of randomness when you loot containers and such, but this is EA, and that will probably change. Same thing with so many empty containers. I think they just haven't filled them yet due to it not really being an important testing tool for the game. This EA is for testing and making the game itself better, so in this regards, just be patient.
As far a a loot all button, you might have to wait for the modders on that. If it's optional, then fine, but I personally like to actually search and loot things. In this case, it's personal preference.
