This funny to read! I drive Codex TUI daily. In the past, I paired it with VSCode for better code navigation and file reading; seems similar to what you are saying or do you also mean Source Level Debuggers, etc.? But, I eventually worked on Kitty terminal typesetting instead and now reading the files with my gloss tool [1]; combined with Rex blocks it's really nice, easier on my eyes.
Thanks for Ratatui, which certainly has a top tier name, and also has had tons of great software written with it! I've been inspired by much of that ecosystem, especially the charting libs. The weird GUI stuff I'm doing with Kitty+Bubbletea, can certainly be done on Ratatui, in the spirit of Makepad. IMO, Golang needs this more than Rust.
