Maybe one day... We many more dev help to get this granular on options. Each option has a maintenance cost.

i think a library should be doing much of this, i saw you adopted and modified one?
Nope, this is all main dev time. Each app must re-implement it. There are too many new screens to manage these lists well.
We don't even have a way of following people on lists yet. :(
Lot's to do.
