Pin Interaction - Customize Discover

I found this tap control (you may familiar with already 😃) in the Google app and decided to express curiosity as an animated prototype.

With this pin control, the user can customize the discover pattern of topics which are listing in cards.

The user can tap 'More' to find more cards for the interesting topic. If the user does not want to unfollow a topic but want to get less of it in Discover, tap Less.
