Show HN: tiling windows for MacOSX in less then 200 lines of code (github.com)

Nice work. One thing I think is very beneficial for this type of window management is being able to set a custom horizontal split, i.e. something other than 50/50%. Then you can have a "major/minor" approach, where you put things that need to be wide, like web browsers, in one side, and things that are still usable narrow in what remains.
