There's a spectrum of these. There's terminals that have their own modes, like Termite. There's also terminals that have their own scripting/extension frameworks, like hyper.js or secureCRT.

My personal favorite is Emacs. It's the only environment I've ever been able to rig up that's truly, fully hackable. Since terminal output is treated like any other text buffer, I can roll just about any package I like on top without issue.

In particular, this solved my ssh woes. There's no need to reconfigure my terminal dozens of times each day, because all my preferences and tweaks exist on a higher layer.
