"I use replacements for almost all the built-in apps. I use a custom launcher. My editor config Git repo is approaching ten years old, and my shell config Git repo is almost eight. There are standard interfaces to per-application Preferences and keyboard shortcuts. When I sit down to use someone else's Mac, I have no idea how to use it!"

I run an environment, on OSX, similar to this although (I assume) much less ambitious in the customization.

My biggest problem is the lack of focus-follows-mouse. I had this in the snow leopard days with an add-on called "mondomouse" which is abandonware and I attempted to solve it with "dwellclick" but that isn't really designed for what I need and doesn't work.

Now I see that in very, very new versions of OSX there is some buried setting in accessibility that does honest-to-god focus-follows-mouse (as in, raise window as if I clicked it when I hover over) ... can anyone confirm/deny ?
