If I understand it correctly you want something like what Mastodon has, splitting “your stream” and “world stream”, being the second the default one. Am I right?

That’s one thing that should be upgraded. There has to be a way to link your accounts in Lemmy, PixelFed, Mastodon, … so “follow” becomes “follow with” and choose the service.

Search with the magnifying glass icon. In Discover maybe you can find something.
