there is a title bar NAG in the middle of the screen, it is floating and stick in its place ,look at this picture: i refer to it by a red arrow:
indeed it causes some pain in my heart, there is no such nag in the previous documentation.
since i do not know to whom i may talk, i hope from the documentation administrator and designer to re think of this annoyance, and if someone from the good people of this community find it annoying to support me.
