Would be nice to have a different wrapper around Claude, even something bare bones, as long as it's easy to modify. Claude code terminal has the jankiest text editor I've ever used -- holding down backspace just moves the cursor. It's something about the key repeat rate. If you manually press backspace repeatedly, it's fine, but a rapid repeat rate confuses the editor. (I'm pretty sure neither GNU readline nor BSD editline do this.) It makes editing prompts a giant pain in the ass.
