It's too much to ask a user to disable other relays to get this UX; best for the application itself to multiplex the user's relays, index them, then provide this view into their content.

Yes, I agree that the experience is not good.
I'm not a developer. But I would find value with an option that resides on the client.
With following options:
1- Algo on/off
2 - weekday lunchtime Algo. I have a few minutes and want to see higher weighted content based on specific criteria
3- weekend evening Algo. I have more time and different attributes are applied to content that is more broad.
I can set this on my end via my client and effects no one else's feed.
