For mac users interested in tiling (ish) managers, but not willing to make the leap DHH made, I highly recommend the Magnet app, which gets me most of the goodness he is demoing in the first part here ... (and maybe a little more?)
How Aerospace (and others) degrade under heavier system load, etc (again, not b/c they are poorly written, but b/c macos inherently does not want these kinds of packages to even exist and makes things very hard to say the least, if not impossible, requiring some very awkward gymnastics) made this incredibly frustrating at the worst possible times.
