Colorful Tmux panes
Thanks to this commit, we are able to style an individual pane in Tmux. You will have to build Tmux from source to do that. Try:
$ tmux select-pane -P 'bg=green'
And you will get something like:
We could use that to highlight an important pane.
I have set key-bindings
M-4 to different background colours, and
M-0 to the default colour:
bind-key -n 'M-0' select-pane -P 'bg=default' bind-key -n 'M-1' select-pane -P 'bg=black' bind-key -n 'M-2' select-pane -P 'bg=green' bind-key -n 'M-3' select-pane -P 'bg=blue' bind-key -n 'M-4' select-pane -P 'bg=red'
Thanks @thomas_adam for mentioning this feature in the #tmux channel.
