Show session name if applicable?

[rieje]

I use tmux with multiple nnn instances as split windows and a wrapper that sets this up. It would be nice if nnn shows its session name if it has one for improved context (remembering which split window has which nnn sessions). Also, to save sessions, I quit that particular nnn session and then start it but I need to remember which session to restart (cannot always rely on shell history or do not prefer to).

There's very little space in the top and bottom rows of the main screen.
Perhaps add to the help screen if it's not there already? Please raise a PR if that's OK.
