In Vim, you can move a window to an edge of the viewport with H/J/K/L. Vim will make sure the window occupies the whole edge and resize/shift the other windows around it. Is there something similar for tmux? move-pane doesn't seem to have an option to preserve sizes like Vim does for you. rotate-pane is not the same behavior either and does not guarantee the pane will find the correct edge.
