All who gather here, I’d like to share a few words about the just now removed Deck Review button. Just yesterday I met this button. Just today, I taught a user the functionality of this tool and alas, they have been taken from this world too soon due their long time conflict with the “load time” family who seeks to support the addition of many more future decks. I hope they rest well in the code archive, perhaps waiting to one day be revived in a new form by the Bunpro developers.
R.I.P little guy 
Goodbye to my favorite feature, hello to my newfound anxiety from seeing my reviews all lumped together.
Just a note, it is still available within the deck page itself, just not on each little deck tile.
Really missing the feature so much slower to see how much I have due on a specific deck.
Now thinking of deleting my other decks so it’s easier to focus on what is more important for my exam. The deck page to see what’s due loads slow too.
I hope any changes like this can be more visible in the future because this morning I thought I have no reviews due!
Just a heads up to everyone missing the review button. It is back!
Given the unexpected sadness about this change, we have brought the little guy out of retirement on just the My Decks page. That means all the decks shown here (learning, custom or bookmarked) will have the button available.
The prodigal son returns!! Thank you so much. 
Thank you so much
