Follow packs are a nice step, but I'm not currently inclined to use them. What I would be interested in is having them as discrete lists or filters that I can flip off or on.

Say, I'm in Prague, and I want to see all notes from everyone else there. I subscribe to/activate the BTC Prague list. I get the benefit of the content, without having to commit to following. If I like what I see, I can tap another button to follow individual npubs.

When the event is over, I deactivate/delete my subscription to the list.
