The biggest pain point with TUIs has always been the design iteration loop. You're basically writing code blind, running it, tweaking numbers, running again. It's like writing CSS without a browser preview.

Something like this could genuinely help for the layout/positioning phase, even if you still hand-write the interaction logic. The debate about whether these are "real TUIs" kind of misses the point imo. Textual and Ratatui already blur that line with mouse support and rich widgets. The ship sailed on pure keyboard-only text interfaces a while ago.

What I'd actually want from a tool like this is to export to multiple TUI frameworks. Right now you're locked into one ecosystem and the code export isn't even working yet, which makes the whole thing feel premature.

A TUI library with hot reload would be pretty cool
