Same, so I entirely did away with pinned feeds. After 4-5 pinned feeds, they don't really serve any purpose.
Being able to change the order is all that's needed imo.
i only use it sometimes, i like to switch it up. i'm actually really invested in feeds. i like that they're given equal weight.
to my mind, they're not really "nested" or "sub" to the main feed, logically.
a vertical list WOULD be nice somewhere tho. maybe a swipe to reveal instead of a tab?
