I don't understand why this can't be done.
all we need is a shortcut to the feed. in theory, even with nova Orr similar running, blink feed is still doing its thing in the background, we just can't get to it.
I'm sure some one like nova could do:
say you have 3 home screens set, instead of infinite scroll,
you could have the left most side of home screen one set as a shortcut.
I then you could set the short cut to blink feed (or anything else you might want to use)
it would be pretty much the same as we have but with a custom launcher.
does that make sense?
