The application menu where it should be
Kubuntu Edgy by default gives you something that Apple users are well accustomed to. I am talking about the placement of the application menu bar.
By "application menu bar " I mean the menu that contains items such as "File Edit View" and so on.
It's pretty obvious that a user can only use a specific program's application menu at the time. So, why waste precious screen estate by showing the application menu for every single application open?
Basically, Edgy's default (if you're using Kubuntu) is to have the application menu right at the top of the screen. The menu will change according to which application has the current "focus".
Ubuntu people won't have this luxury. Ubuntu is based on Gnome, which is based on GTK2. GTK people are very, very strongly against the idea of having the application menu at the top. I can see some points of their argument: what if you have two monitors? What if you're using a multi-window application with different menus in each window? However, I can also see a lot of screen real estate wasted, and a lot of users who want such a functionality - those people, luckily, will be able to use KDE!
If you don't like this behavior, you can always change it. Just start the KDE Control Center, Desktop, Behavior, and change the "Menu Bar at Top of Screen".
I doubt you'll ever want to go back, once you get used to having the menu bar at the top.
