Creeping features

I don't like the pantheon terminal outlook on the Elementary OS. It is better than others including the one in OSX (I tried only the default one though). But why the heck does it have all these bells and whistles like header, tabs and so on? Just asked a question at stackexchange and got a hint how to do it. So, long story short, I tried to strip all the decorations with some simple hacks, without diving deep into the GTK+/Glade and so on. But the problem has to be solved fundamentally, with some settings. Anyway, I put my thoughts there, in the initial question.
And yes, it is just another spin-off from the main topic of hacking the GIMP. Just a spin-off...
