I met the following confusing sentences during my reading:
1. This small remote-control robot is really powerful. It can perform 67 preprogrammed functions. You can even program your own function---which sadly does not include doing windows.
What does "doing windows" mean?

2. There is nothing more complicated than that about Americans tipping in restaurants.

From the sentences above, could I conclude that how to tip in the United States is not complicated? Personally, I think it is the other way around. Am I right?

3. Tony Blair faced new allegations on Thursday that he misled Parliament and the public in making the case for the war in Iraq he disclosed his chief adviser's written opinion raising questions about the legality of the war.
IS "make the case for the war" a fixed phrase? What does it mean?
Also I get mixed up with this long sentence, especially the transition between "in Iraq he disclosed..." Should I add one conjuction in between?

1. Doing windows means either Microsoft Windows, or it means cleaning windows in your house.

2. There is nothing more complicated than that about Americans tipping in restaurants.
It refers to "that" which probably the writer has just explained.
Tipping in the USA is usually fairly straightforward. You add about 15% of the total bill if you've had decent service in a decent restaurant.
You don't tip in McDonalds and other fast food restaurants.

To make the case for something means you try to justify it by giving all the reasons why you think it is a good idea.
