Find a way to highlight focused window in Gnome

[curusarn]

Temporary highlight

The ideal would be to have a temporary highlight on any focus change. It seems that this would have to be added to each way that switches between windows and there are 3 that I use. ("alt+tab", put-window extension, and switcher extension) Patching something in the Gnome itself plus two extensions is insane.

Permanent highlight

Somehow highlight the active window more than it is now. Plus don't ruin the looks of the theme while doing it. Plus do not make different windows inconsistently themed.

Maybe I could do something with the window title to make it clear which window is focused.

It would be great if I could do something like: ❮❮❮ $actual_window_title ❯❯❯ for the active window. EDIT: Not really because titles can be really long. (e.g. https://github.com/ohmyzsh/ohmyzsh)

Some border or color around the title without making it look bad would be nice.

Or alternatively, make the inactive window titles/top bars shaded, very light or something.
