One I used to love back in the 80s/90s was GFA Basic on the Atari ST. In a similar category of TUI (mostly, it did have mouse control and menu bars, but you didn't have to reach for them) with great auto-indentation and code folding (features not common in mainstream editors at the time) and instant compilation and error checking.

It took many decades for me to get that kind of flow back for mainstream programming languages on modern computers. And modern IDEs still have higher latency than they should.
