Thank goodness for this. I would say you've succeeded at those goals - sometimes I go deep into tinkering and other times I am focused on something else. i3 is on the short list of software that I can tweak to my liking and then ignore for years without concern that my environment will mysteriously break from an update. I really, really appreciate that, kudos.
