I'm super impressed with nostr:npub1l5tgujhhn7pyxunuaxwklaune7ak8yvf8zg0slsr45fmkhrrhgeq37qq33 as a Mastodon client! Things I love:
* cross-platform FOSS static web app that you can self-host
* the UI/UX is opinionated but simplified in a way that works for me with a polished look and excellent subtle animated feedback
* the Progressive Web App works great 

Features that all clients should adopt (the creator invites it!):
* threaded replies 👌🏽
* showing threads chronologically with thread indicator/counter 😘
* boost carousel 👏🏽
