You know #lists on #Mastodon ?

I have them - sort of - themed, but you could just have them numbered if you use web interface.

Then you can put people in different numbers according to how much you want to see their posts.

The web interface extends off screen to the right if you add more lists, so you can kind of have some users partly hidden.

It really works though to split your follows up a bit. You get to see stuff that otherwise might get buried.
