stepping back and looking at the big picture, I get this same feeling about many apps. Especially ones produced by Google, when you upgrade an app, suddenly the UI is totally new and you don't know how to use the app in the same way you did before. Yes Google might not have chosen poor words in this case, but it does create friction when you switch around the whole UI. The example I always cite is when Microsoft switched the whole UI in Office from the 2003 version to 2007 version. People who had mastered pivot tables were suddenly up the river without a paddle
