Handle large state objects in the UI

# Problem

Large state objects will (a) kill the UI, and (b) make looking at data difficult.

# Context
I have a large list of objects 1K+, that I am processing and iterating through. The UI needs to handle this case.

# Possible Solutions

1) limit what is returned from the backend. Allow people to dig in, and open up a specific modal if the object is of a certain type or size.
2) do some smart caching on the UI? or only store "deltas" between steps?
3) do something else?
