How to automatically rename tmux windows to the current directory

# be sure to see note* below
set -g window-status-format '#I:#(pwd="#{pane_current_path}"; echo ${pwd####*/})#F'
set -g window-status-current-format '#I:#(pwd="#{pane_current_path}"; echo ${pwd####*/})#F'

# status bar updates every 15s by default**, change to 1s here 
# (this step is optional - a lower latency might have negative battery/cpu usage impacts)
set -g status-interval 1
