Shell emulator with tabs for gnome/gtk

[csj <csj@mindgate.net>]

I'm looking for a shell emulation program that has tabs (like the 
one you see in galeon or gedit). The one I'm presently using, 
powershell, does have tabs (which I found, thanks to apt-cache search). 
But I have some issues with it  ;-). Now are there any other gnome- or 
gtk-based shell emulators that has a similar feature to let me keep my 
desktop "as uncluttered as possible"?
