#[0] How about on the profile page is a bell or similar to “subscribe” to the posts of the npub. And an additional tab on the notifications page where every npub you are “subscribed” to is displayed with stats for “unread” posts. And you click through to a feed of those posts, or just to their profile.

My use case is I frequently think I might be missing posts from particular users unless I am constantly on Nostr watching the waterfall. My current method is just scrolling the feed for a recent post from a npub I want to see possible updates from then click to see their profile so I can see all posts over a time range.
