I love "dotfiles" in general, and IMHO this repo makes for excellent reference material. There's always something more to learn, and IME (paid to use computers since 1998) time spent improving your tools is usually well-spent. Of course tinkering can be a rabbit hole or time-sink of a hobby, but leveraging others' expertise (via dotfiles repos like Mathias's) can mitigate that risk. More generally, taking the time to grok the system you depend on -- and shaping it to your liking -- is one of the most sensible things you can do.
