After a quick test this looks incredibly good and fast. I'll use it as a terminal for the next weeks to see how it goes, but I have good feelings. Thank you so much for writing it.

EDIT: WOOOW, for me this is going to be a game changer. I was just working at Redis stuff outputting a ton of debugging info and results, and normally the terminal was the bottleneck, and here instead it printed half million of results in the blink of an eye. And then I could go back in the history without any performance degradation. I love this: for development of systems it makes a big difference.
