KDE4 Expanding Icon Questions

One thing in common with any KDE4 theme seems to be a new icon concept. When the mouse is placed over the icon, it expands into a larger rectangle with widgets. Personally, I don’t care for this expanding icon concept:(; here are my questions.

  1. What is the expanding icon behavior called?
  2. Can expanding icon behavior be turned off in the KDE configuration application?

Thank You!
