Fedora's insane menus "feature"

I have been fairly impressed by Fedora (core) 2, but I have stumbled onto a "feature" where you can't edit the menus. You can add items to your dock/quicklauncher, but the main menu is not modifiable by any magic that I have scene. So my question for Redhat and the Fedora developers is what the hell are you thinking? Granted, Fedora is not yet an officially released product but you have been working on this for many, many months and you still can't edit the menus? If this isn't fixed is short order I think I will have to install my own version of KDE or switch to another distro. Is there some wonderful reason for this? Is there a grand feature that is not yet viewable on the horizon or is this just a train wreck that you created by trying to get gnome and kde to look and feel the same?
