There is nothing more powerful than having the perfect configuration for your preferred application. For most unix tools the configuration is stored in hidden files (also called dotfiles). Very often the default configuration of an unix application is good, but not perfect for your own workflow. But luckily its very easy to configure your tool exactly how you like it. It's very common to share his config so other people can read it and apply useful parts of it to there own config.

My dotfiles exist in a Git repository over at GitHub. It contains most of the config files i use for my daily work. This includes tools like tmux, vim or ksh.
