I&#x27;d be curious to know how this software compares with Amethyst. I&#x27;ve also been using Amethyst for some time with no problems, but it is sometimes a bit sluggish. I have so far assumed this has more to do with unavoidable limitations in the OS X gui ecosystem. It is written in Objective-C, is available on homebrewa and has a binary distribution available, provides a gui configuration manager, and seems to include all features claimed by kwm—including focus follows mouse. But if I knew how the two projects differ and, in particular, what kwm provides (or plans to provide) that Amethyst doesn&#x27;t, I might consider giving it a shot.
