On Anki Desktop and AnkiDroid, the green count of “cards to review” and the blue count of “new cards” are grayed out when the value is 0.
This makes it really easy to skim the deck list. You can immediately spot which decks still have cards that you need to review today.
On AnkiMobile on the other hand, 0 values are not grayed out. This makes it hard to skim the deck list.
Feature request: add the same behaviour to AnkiMobile (iOS), that is gray out 0 values. Thanks a lot!

Versions: AnkiMobile 2.0.87, AnkiDesktop 2.1.54.
