I have all my windows centered but pyramid stacked. I can see a bit of everything but my main browser is in the center. Slack is in the upper right, and the browser leaves a bit of the Slack screen open. I keep Obsidian in the lower left such that I can see the organization panel.. it helps me keep a mental map of the notes I'm working with.

In the center are two Chrome browsers representing two separate profiles.. a personal profile for some flows, and a work profile for others. Again, stacked so that I can see most of the tabs.

I've never dared to dream that I could combine this habit with some Hyprland-style "spontaneous windows launched by keybinds". I'd love that. A prime stack of core windows and an omega stack of ephemeral windows.

When I have multiple screens I also tend to stack one above the other, as opposed to left and right.

Corner case all the way.
