One minor problem is that we still haven't figured out which light switches are for which lights. There are a lot of lights in this house with two and three switches each, so one can, for example, switch on or off the main stairwell light from upstairs, downstairs and the landing. Potentially quite convenient, but it makes it a bit confusing. And it is a big house with lots of lights, so I am still learning which ones are which. I actually stopped to count them today, and there are 71 light switches in our house. Is that normal? I don't think that's normal....
