Turbo Vision is odd. It's a backport of a graphical UI (Windows 3.0) to text mode. It was exceptionally well done in both end user and developer ease of use and caught on. But I doubt it's the optimum for a text based UI, at least for most applications. Keep evolving!
IIRC both Windows and TV where modeled after the IBM Common User Access ( https://en.wikipedia.org/wiki/IBM_Common_User_Access ) interface style, which was a somewhat big theme in the late 80s and early 90s.
