Re: I miss 4NT
4NT/4DOS still exists, and is still updated and developed by the orignal author. It's just that the name changed ... it's called "Take Command" now.
There's even a free-but-without-support version called TCC/LE.
On Windows I always have a TCC window open, and usually an MSYS2 BASH window as well (gave up cygwin years ago), but I never ever use Powershell.
