> Customizability ends up being pretty important for serious developers who are always in the terminal.

Ironically, I would say customizability ends up being pretty important for serious developers attempting to avoid working. I can't say my terminal itself—as opposed to the shell—requires any serious modifications at all. (I rewire the left option key and color schemes, and that's about it.)

Which one is the killer feature? The ones listed in that article all seem like extremely minor differences to me.

Thanks for that, although it similarly hasn't swayed me :D
