As per my comments elsewhere in this parish, I was rather fond of the 'edit' editor in DOS. I think the nearest modern equivalent would be Nano[1]. Putting a native port of Nano into Windows (using the Windows spellchecker) would be handy. Well, yes, handy, but I would have thought that anyone who was likely to use it would already be using Nano/Vim/Emacs/whatever in Cygwin or WSL.
