Let's try an keep the thread focused on actual objects.
I'd like to see more ship objects that we can interact with. There's several Mirandas, and freighters, and fighters, and a few others but we need more variety. (If I want to be able to fly up to Reman Dreadnqight and scan it I should be able to.)
I'd like to see basic ship locations. Like just a simple room of certain types connected to a hallways (which deadends around a corridor). I was dismayed to discover there's no transporter room in the Foundry, even though we've seen it in other missions such as the tutorial.
Must have rooms:
While we're at it, a lot of that could be solved if we just had access to the generic small/med/large interiors. Why aren't those included in the Foundry? Seems like a no brainer.
