How funny. I just spent the weekend AI slopping an FFI wrapper around notcurses because I couldn't find anything else. This looks amazing!

Since you asked for ideas in a different comment, here's something I put into my notcurses wrapper: grid and flex "css" layouts. Meaning the ability to say whatever.fixed(cols,...) and whatever.flex(:fr1) or whatever.grid(:fr1) and the ability to do a "grid-template-areas" style ascci art ala https://developer.mozilla.org/en-US/docs/Web/CSS/Guides/Grid...
