Menu Editor and window behaviour control in Gnome
 

Hello everybody,
My distro is Debian Lenny. I have used KDE for the past five years. Now, I am trying Gnome, because I experience font corruption in OpenOffice in KDE environment. As the one very much used to KDE, I want your help on two things.
First, how can I edit menu items in Start menu?. In KDE, right-clicking the K menu opens Menu Editor dialog, which was quite easier.
Second, can I control window behaviour. For example, if I want Iceweasel to always open in a maximised window, what should I do?
Thanks in advance.
