Master House Command.

Yeah, that's basically it. Let's say you're in a house that you have the master key to. When you're in this house, a little house icon could appear in the upper-left-hand corner of your screen, and when you click on it, a list appears on your screen which you can scroll through, and select for it to be on or off.

A few examples would be:
Store mode (If you're using this house as a shop, the icon on the map would change, so you could easily see where all the shops are on the island.)
Spell-casting mode (It could have a sub-screen for this, which allows you to select which spells are allowed to be cast and which aren't.)
Furniture-move mode (As it is now, only the holder of the master key can move furniture, but this option could allow them to extend that power to people who hold key duplicates, or to everyone.)

There are probably more options that can be added later.
