I love continuous feedback.
I set up automation in my development to run quick tools like code formatting, linting, and unit tests together.
I'll use tmux to split my terminal into an editor window on the right, and on the left, I'll have a tool like watchman or entr watching for changes to my code, and running those tools e.g.
find . -name "*py" | entr make continuous
I also have some conventions about my tmux windows. Window 0 is where my music client lives in pane 0, and usually I'll run things like homebrew updates in other panes there.
I have a tmux keybinding that sends the "Next song" key to window zero pane zero. No matter where else I am in that terminal session, that keybinding skips to the next song.
I have another pair of tmux keys that activate/deactivate a particular openconnect vpn connection in a new pane, with a pause so i can see it complete, then it goes away. Part of my tmux status line is a single character - a C or a D, that indicates that vpn connection status as connected or disconnected.
