Alternative to Pixel Saver (remove title bar and place buttons in top bar)

Question

I've moved from Fedora with gnome-shell 3.16. I'm seeking a plugin that works like Pixel Saver, which generally removes the title bar and places its buttons in the top bar.

Answer 1

This is not possible for two reasons:

1. Window decorations are now drawn by the application itself. There no longer is a separate title bar.

2. The panel does not support such an API.

Answer 2

Yes, Pixel Saver stop working in new Gnome

But Unite works well on Ubuntu 19.04. One more alternative is gtk-title-bar
