When will we be able to move furniture and other items around the hangar?

That comes after the advent of persistence, I believe.

Persistence and grabby hands are both coming, and we'll have more on that when they're close.

If you want to follow the development of persistence, pay special attention to the Jake Ross segments, the Austin segments of Around the Verse. That's where you're going to learn most about the progress on persistence. And grabby hands, I imagine you'll probably hear about in either the UK or the LA segments.
