Doing it live means editing the deployed code of a deployed site.
8 tmux panes in my primary window:
5 tailing logfiles
1 command and control (managing daemons)
1 general purpose
1 vim with 46 splits including code files from the site environment's site-packages
directory and miscellaneous server configuration files.
The 12 other tmux windows contain one-off purposes that I have yet to document properly or account for otherwise. Leaving them open allows for most ready access to do that at a later date.
Vanilla tmux and vanilla vim on vanilla Debian are extremely reliable long term.
