Disappearing title bar is up to applications developers, not shell but the trend is to hide them when window is maximized.

But you just said you love title bars. They are fat space-hogs by definition. Regardless of theme.
>Why have you removed configuration options that you had in gnome 2? I found a lot of what i was missing in gnome tweak tool, But it seems like someone has decided that I don’t need those options, and it makes me feel stupid.
Because 1. GNOME is not a final product. It'll never be. 2. Regular users really doesn't miss them.
I don't think its contradictory that I want title bars and thinner theme. The title bar serves as the main handle to move a window. When its taken away it makes it hard to pull the window out of being maximized, depending on where there is free space that will let me drag a window around to pop it out of its maximized state. The title bar serves a purpose. The extra padding on tabs, buttons and menus doesn't help me much as I know what i am looking for.
I fully understand that gnome 3 isn't a final product, and like basically all Open Source software it is available "as is" and without any guarantee that it is fit for your purpose. I would have thought that the "regular user" for a system like gnome was a person like me. I guess that is no longer the case, which is fine, its just hard finding a new desktop environment that i'm comfortable in.
