Thanks for asking. That nostr is a protocol you may be able to find what you are looking for from various other clients or front ends such as https://nostr.band/

I have seen a trending tab on something I've used recently, but digging through Amethyst now, I'm not seeing anything today (maybe it was a Web client)

Takeaway, as a protocol there are many ways to see the nostr data. If it's not available on one app, it likely will be on another.
