I just shipped NIP-51 list support in Habla. You'll be able to link to lists with the usual NIP-27 nostr: syntax.
Check out this example from my muted pubkeys:

And my pinned notes:

I hope clients start supporting NIP-51 lists more, Habla is ready for including them in your long form content (even lists that contain other lists 🤯).
