How do you manage multiple monitors with MacOS? I was doing this until recently and every single login involved rearranging my windows because MacOS moves them all to whatever display woke up first.

I finally got sick of this and wrote a Hammerspoon script to deal with this. The config looks like this:

      local dualLayout = {
          {"Firefox",       nil,         primary,   topLeft,             nil, nil},
          {"Preview",       nil,         primary,   topLeft,             nil, nil},
          {"Sublime Text",  nil,         secondary, topHalf,             nil, nil},
          {"Slack",         nil,         secondary, topRight,            nil, nil},
          {"Notes",         nil,         secondary, topRight,            nil, nil},
          {"iTerm2",        nil,         secondary, topRight,            nil, nil},
          {"Safari",        nil,         secondary, topRight,            nil, nil},
          {"IntelliJ IDEA", "cursive",   primary,   hs.layout.maximized, nil, nil},
          {"IntelliJ IDEA", "community", secondary, hs.layout.maximized, nil, nil},
      }

Now when I connect my two external monitors, a quick Ctrl-Alt-Cmd-R lays everything out. It's crap that I have to, but it saved my sanity.
