Obsidian is great and open source; I actually want to build a plugin compatible with nostr:npub1w0rthyjyp2f5gful0gm2500pwyxfrx93a85289xdz0sd6hyef33sh2cu4x . Funny story, my very first nostr idea was writing such plugin 😅
That said, like you say, nostr:npub10awzknjg5r5lajnr53438ndcyjylgqsrnrtq5grs495v42qc6awsj45ys7 , a nostr native tool will be able to leverage flows that were previously not possible, in general, I think “bridges” narrow the creativity field
