If you manage a lot of ssh connections, I can see where this would be useful. I’ll borrow his screenshot since I only have one connection and so it doesn’t look very impressive.
You probably get the point just by looking at that though. You’ll have to set up a hosts file with your available connections and the addresses for each.
After that, dialog takes over and you can skim and select from the list. Direct, clean and straightforward. Once again, it seems the simple solution might be the best.
