tmux-resurrect saves all the little details from your tmux environment so it can be completely restored after a system restart (or when you feel like it). No configuration is required. You should feel like you never quit tmux.
exa is a modern replacement for ls. It uses colours for information by default, helping you distinguish between many types of files, such as whether you are the owner, or in the owning group. It also has extra features not present in the original ls, such as viewing the Git status for a directory, or recursing into directories with a tree view. exa is written in Rust, so it’s small, fast, and portable.
