Feature Request: Square borders

[rockofox]

I'm not sure if this is in scope for this project, but I'd love to see square borders akin to older versions of yabai, cxa's yabai fork and tiling WMs on Linux.

I will add an option for square borders later today, however, I will probably do it a bit different than the alternatives you have mentioned.

Awesome! Thanks for the quick response

I have added this just now. The way this differs from other implementations is that the border is only square on the outside but is still rounded on the inside. This is because the standard macOS windows are rounded and else there could be gaps between the window and the border if the border width is too small.

Is it possible to draw the borders over their windows and inset from their windows edge? This would let square borders cover up their windows' rounded corners.

See #37 for details about how to achieve truely square borders.
