For example, if the height is greater than the width, I'd like the tile to be split vertically. If the width is greater than the height, split horizontally. Rationale: There is a small, but noticable cognitive load when manually prefixing my action with mod+v, mod+h. If this is not currently possible in i3, would it be worth filing a ticket to add a conditional tiling policy indicator to .i3/config?

Seeing what you did there gives me some other ideas about using xdotool.Tue, 18 Nov 2014 21:28:50 +0000https://faq.i3wm.org/question/4966/conditional-window-splits/?comment=4968#comment-4968
