Reminds of the DOS order management software I used in the 90’s.
ASCII tables, text only, with F key shortcuts. Hard to learn but blazing fast once you did.
Nothing modern approaches it.
Reminds me of modern IDEs -- developers, both old and new, are too lazy to learn a complex IDE to speed up their work, even though it's their main tool for making money.
As a support engineer at IBM we used a mainframe system called NRCPMA iirc... I think NR stood for Northern Region. Accessed via a terminal emulator, fully customizable with macros, fastest tool I ever worked with indeed, once you climbed the initial learning curve.
