I tried to follow the trend and add some gaps between my windows for aesthetic purposes, but other than looking nice I can't stand it at all.
It just feels like I'm wasting so much space, looking in to tiny box windows, and even worse, it makes me miss when I go to grab scrollbars, click outside the edge of my gaymen window, etc.
But it does feel like it lowers stress tension in my head compared to having my screen completely covered in content.
