Nice clean tmux setup with practical defaults. Switching the prefix to Ctrl+a makes navigation faster for anyone coming from GNU Screen, and the vi-style copy mode bindings are a great touch for keyboard-heavy workflows. I also like the custom status bar colors and Powerline separators — simple, readable, and not overly bloated. The automatic hostname rename and mouse support make it convenient for both local and remote sessions. Solid starter config for developers who want a balance between usability and minimalism.
