I recommend turning on the title bar icons in future releases of Fedora. The GTK+ folks have put "Adding a Title Bar Icon", as the number 3 tutorial, wouldn't it be nice if, when the student has built an application with his/her own icon, it actually shows up on the title bar!!
How to turn on title bar icons:
A skin like "glider" for the gnome skin "window theme" would add clarity to the title bar. Also, someone turned on the flash screen accessibility feature in F17. As a programmer it wakes my wife up, even though I am two rooms away, flashing a 40 inch plasma TV is not good. Simple pull down menus also make much more sense than the giant pile of icons. Most GUI textbooks and market surveys suggest no more than a 20:1 menu ratio. "Applications" violates both market survey and psychological studies. If you wash dishes and throw them all in a big tumble on the floor, or I take all office cabinets and chuck them out in a heap, you've got the "applications" window!!! For most programmers this means 100+ applications with no way to sort, categorize, view thumbnails, sort by date, etc.
