The UI and interaction design for adding an item in a Gift List product.
I used Principle to make the video, and GifBrewery to compress the gif.
Not sure about the Floating Action Button pattern, but here it just worked out as the most efficient way of ensuring the user doesn't need to scroll all the way to the bottom to add something new.
The only thing I'm unhappy about is the graininess of the final gif. If anyone can recommend settings for GifBrewery, please send them on.
