I’ve suggested this before, and from what I’ve seen, so have others.
Can we include an “Open All Packs” button with perhaps a Gallery view of all the cards that came out?
Even if it was limited to opening all packs from a specific expansion, I’d be ok with that.
I’d be fine if there wasn’t any gallery view after at all. You can search for “new” in the collection manager.
They will never do this because it will reduce the excitement of getting new cards.
And frankly, I’m OK with that. The major objective in this game is to grind to get card packs. I’m happy that they make the pack opening process exciting! 
you spelt “more dust” incorrectly
Also you spelled “Incredibly boring” as one word. Exciting sounds nothing like Incredibly boring so not sure how you made that big a mistake.
But then people wouldn’t see streamers open packs with their privileged rng, and think “man I should buy some packs! look at that! he just got 10 golden legendaries.”
