What do you mean by take back? If you mean make it smaller you can do that in the new station defaults section in the company menu

I think he might be talking about the catchment area preview. Previously we could see it even before laying down the station blueprint.
It was actually easier that way to see if the station was well located or not. I agree :)

That is actually possible, but this setting is turned off by default. Just tick the box 'station catchment area' under the Map Options menu (the most left button in the top right bar)
