The great thing about running everything in a terminal is you can copy anything that is shown in the terminal. Frustrating when a GUI app won't let you copy some text it's showing and you have to retype it somewhere else by hand
On net I'm not sure it's an improvement. Being a pure ncurses-esque console app limits the richness of what you're able to display. Native controls and dialogs are in fact a good thing and not a cardinal sin.
Huh? Just use Ctrl+Shift+V or even Ctrl+V if your terminal emulator of choice allows that? I don't see where the minefield is
