Hello, maybe this is a late answer but maybe still helps.
Look you can’t use your google+ url as the user ID, you have to use your user ID number.

First of all thanks for this great plugin. I have question regarding this new feature.
What if I don’t need any of the search functions, tag or anything the landing page does?
I have always used wordpress and never had to change the default behaviour of the main menu. I just create pages and they appear right there, that’s the way it has always worked, and I’ve been confortable with this. Then today all of a sudden I have an invading page in my main menu, so I have to create a menu with all my page links? I don’t feel this confortable since is messing with the default wordpress behaviour.
As you are saying this is a nasty behaviour and it should be optional, One should be able to turn it off or on.
