Implement stack-limit for further defining how stack windows should look Using this command, you can limit the amount of columns or rows for a stacking container. This allows for better usage of screen estate when using stacking containers with many clients. Examples: i3-msg "stack-limit cols 2" You will now have a stack window which has two columns of windows.
