The future repeats the past. This looks much like the back-end systems I used to design on TurboPascal in the late 1980s / early 1990s.
Well, you’re in luck! There’s a modern version of TurboVision that works on modern systems. I used it the other day to show tvedit to some of the folks at work who were using nano. They were kinda mind-blown by the fact that editors in the late 80’s/early 90’s weren’t terrible.

Applications like tvedit were designed for MS-DOS, which offered full interaction with the mouse and keyboard, and many of them were commercial products aimed at a general audience. TUI applications from the Unix tradition, however, were designed for use in terminals with limited capabilities, and were aimed at more technical users (or were created by the users themselves).
User-friendly TUI applications in MS-DOS were succeeded by Windows applications, while the largest revolution in the last 20 years in Unix TUIs has been the widespread support of 256/24-bit colors and UTF-8. Hence the gap in usability between the two worlds.
