Building my first Shopify App. Feedback?

I'm working on a super simple, easy to use storefront animator to release as my first Shopify App.

Here's a demo of the way it looks right now: https://imgur.com/j8yGd48

It's still very simple. I wanted to keep with the basic animations people are most likely to use and not offer modification of them yet. When you select an animation it previews what it looks like with the element name so you can see how it looks! Zero coding required. Easy interface.

What other things do store owners like to animate? Banner text?
