Hi there,
I suggest adding these simple features, please:
1- Adding search bar above. If there are too many packs and someone looks for specific thing, for example, if the app for Anime stickers and he looks for an Anime, he would use search bar.
2- Favorite packs. Also if there are many packs and the user liked some of them and wants to put them in favorites to add them later.
3- Rate us button, for rating the app.

If you agree to add them, I hope you add 2 & 3 in menu navigate
