Nice article, although a minor peeve is that tmux should no more have a capital letter than ls or cp.

But it goes little further than the dozens of similar articles already available. I'd like to see a few tmux 102 or 201 or whatever articles that cover some of the more advanced features such as hooks, targets and IDs, monitoring and alerts, formats and #(), command sequences, if-shell and run-shell, new/neww/splitw -P and shell scripting with tmux, buffers, capture-pane and pipe-pane, find-window and filters etc in the choose modes, pane titles, terminal-overrides, linking windows and session groups, detach -P, remain-on-exit and exit-unattached and detach-on-destroy, the mouse and advanced key bindings, the new status-format stuff in 2.9, and even menus coming in 3.0. And probably more :-).

Of course I know I could write one myself I suppose :-).
