Just like that, I developed the best BlackBerry 10 Nostr client—also the only one I know of, lol. It has smooth keyboard scrolling with shortcuts: a short press of **L** adds a heart to a post, while a long press of **L** pulls up other emoji reactions; **R** replies; **Z** zaps. This is 12‑year‑old hardware, and it runs butter‑smooth. I can only imagine how bad this would run on a 12‑year‑old Android device.
