Enhancement: show username and hostname

[wsh3776]

Describe the feature you'd like

Is it possible to add a setting that can show the current username and hostname

Describe risks you've considered

I think it wouldn't have much risk.

Describe alternatives you've considered

I can use echo user and hostname to show this, but can I show it in the bottom status bar. I often login the remote machine. So if I can see which host I am current in, it would be nice!

I think it can be achieved by edit the script.sh, but I am not sure how to do it.
