Feature: enable -F format string option to show custom information for panes in display-panes command #3074
Description
Issue description
Currently display-pane shows the pane size on the top right corner of the panes. It would be nice to have a way to specify a format string just like for many other commands that would print custom information for each pane. As a corollary bonus, tmux would figure out the size of longest line in the format string, and pad every line of format string to be right aligned, as shown in example below.
Example:
tmux display-panes -F "pane_id: #{pane_id}\n pane_pid: #{pane_pid}\n ..."
would print:
_______________________________________________
pane_id: 1 |
pane_pid: 23434 |
... |
