One of my favorite touches in Fizzy are how notification cards change colors when they're done. And when they're stacked up, you can see slivers of cards behind cards. The peek, we call it. This notifications stack sits in the bottom right corner of every screen. It's pictured below. Just a bit earlier today these were blue and orange and pink (each color represents a phase or column a card is in). When the card is done, it turns black. This way whenever you see a black card you know it's done. No matter the collection, black always means done. So at a glance, I can see progress without having to look any further. I know some of those cards were blue earlier and now they're black. "Stuff's getting done" is the signal that sends. And I don't have to go anywhere to know that, feel that, see that — it's always right there in my periphery. Of course I can click the stack, expand it, and see each individual notification. And I will do that later. But for now, I'm good. I got the feel of progress.
