Iris now syncs notifications/lastOpened and chats/[pubkey]/lastOpened times between your devices over NIP33 tag-replaceable events. It's used to show the unseen dot.

I wrote a Path API that lets you do it very easily

```

path.set('notifications/lastOpened', lastOpenedTime)

path.get('notifications/lastOpened', (lastOpened) => {...})

```

It currently saves publicly, until I get the encryption to work. Don't worry, no one knows how to read it yet 😄
