I would love to see a Floor Plan as an option to click on and view within the tablet tool.
I'm posting this separately, as others have commented that they're looking for a mini map or a drafter/planner of sorts - which I don't feel I need or want.
To avoid 'spoilers', the floor plan could appear/complete as you walk through the home and discover the rooms. That way, for example, a 'secrete room' wouldn't show on the floor plan until you're standing inside it, and you would get to walk through the home and experience it before seeing the floor plan.
I would love to see three toggle buttons/view options for the floor plan: one that displays the original floor plan of the house; a second that displays the original floor plan faded-out and with the changes I have made displaying more prominently; and a third that displays the floor plan only as it is currently (including the changes I have made).
I'm not asking for a specific drafter/planner (something I would 'draw' walls in), as a floor plan itself and other features for the game are more important to me, such as more furniture and items in general, and more size customization and the ability to manipulate and freely move more items.
