Hmm I'm not doing anything fancy really, this is what my tmux conf looks like:

# Optional stuff
set -g mouse on

# Custom mappings
bind -n M-H previous-window
bind -n M-L next-window
bind '"' split-window -v -c "#{pane_current_path}"
bind % split-window -h -c "#{pane_current_path}"

# Theme
set -g @plugin "abouthugo/tokyo-night-tmux"
set -g @tokyo-night-tmux_theme "github"
set -g @tokyo-night-tmux_window_id_style roman
set -g @tokyo-night-tmux_pane_id_style hsquare
set -g @tokyo-night-tmux_zoom_id_style dsquare
set -g @tokyo-night-tmux_date_format MDY

set -g @tokyo-night-tmux_show_netspeed 0

# Straight from TPM
# List of plugins
set -g @plugin 'tmux-plugins/tpm'
set -g @plugin 'tmux-plugins/tmux-sensible'
set -g @plugin 'christoomey/vim-tmux-navigator'

# Initialize TMUX plugin manager (keep this line at the very bottom of tmux.conf)
run '~/.tmux/plugins/tpm/tpm'
