Basically something that us grey beards like in several window managers, it is not supported in GNOME since the version 3.0 reboot, and relates to minimizing a window to the title bar.

You can move the title bar around, and depending on the window manager either double clik to drop down again its contents, or by leaving the mouse pointer for a few seconds hover it, it will temporarly reveal its contents.

Yeah, it took me a while to discover that it was removed from KWin. (I eventually ended up reading the sources). It didn't help that KWin also does 3D effects, so all of my Web searches for "shading" were returning results for "shader" :-(

Oh, gone from KWin as well? Yet another reason to stick to XFCE I guess.

It is gone from kwin because it is really hard to do in Wayland apparently.

The setting is still there (or was there until really recently).
