Hi the Link you provided said to add:
View0_ShowStatusBar=false
However i use KDE 3.5 in Kubuntu Breezy and i had to change it slightly to this:
ViewT0_ShowStatusBar=false
Under [Profile] you'll find this: Tabs0_Children=ViewT0 so you'll have to change View0 to ViewT0.
I tried this but when i open a new tab the status bar is still there, what do i have to do to get rid of that too?
