# Working with UI Store (Interface state)
We are using Vuex to store the application interface state. The store file (opens new window) contains the information about the state of different pieces of UI, such as overlay visibility, wishlist visibility, etc. Of course, you are not forced to make use of it in your theme, but keep in mind that many core components are using the UI store.

checkoutMode- determines whether the user is in checkout or not—useful when you want to change some UI elements or behavior only on checkout (e.g. hide footer)
