The notice about having "access" to the backgrounds is sticky, and takes up one third of the screen on mobile with no way to remove it . . . Why?
You have access. Enjoy!
Edit: upon further investigation, access isn't something that's just thrown around willy nilly! It usually goes for $120/yr!
Fair point. Once you click a thumb to preview the button, it becomes the UI to manipulate the backgrounds. I'll take a look and rethink the setup.
