I am looking for a GTK3 theme for the gnome desktop which allows the following use case:
To close a maximized window, one can move the mouse to the pixel at the very top right corner of the screen and press the left mouse button.
Of course, this can only work if you do not have a top panel.
The problem with most GTK themes is that their close button (even if positioned on the top right corner of a maximized window) is not on the top right pixel of the screen. Some themes even use rounded buttons, which do not cover the top right pixel for obvious reasons.
Using metacity themes, the desired effect is provided by the
Human theme (https://packages.ubuntu.com/bionic/human-theme). Unfortunately, not all windows use the metacity theme.
Any suggestions for a GTK3 theme with the described behavior are welcome, though clean and simple themes (such as
Human) would be preferable.
