Thank you all, for the clarifications :)

yes, please share

There is too many ssh servers, Any scripts/way to import ssh connection details ( sessions.xml from Superputty/mremoteng ) to ssh_config file. Still, I will need to check different groups of servers ( preferably a tabbed list as in post image )

Tabby looks nice. Is there a way to restore session config from Superputty / mremoteng ?
