When I switch windows in GNOME shell with Alt-tab, I find it really hard to distinguish between windows just from the little preview thumbnails.
Back in the old days, metacity (and Compiz, iirc) would draw a border or otherwise indicate the screen position of the window you were switching to. Even better would be highlighting the window in some way. Is there a way to do this with GNOME Shell?
I'm on Ubuntu 18.04, GNOME Shell 3.28.
(Related, but I'm just hoping for an outline or highlight, not necessarily a window preview: Is there a window switcher for GNOME that shows the actual window?)
