Do we want to keep the map switcher?

I can remove it for now since there was uncertainty in our call

Can we remove the text from the category buttons and style the SVGs so the color matches the rest of the app (like blue/white)?

Yep, we should be able to. I'll change that now.

Looking great. I made a minor change to get both address URLs to HTTPS. Ready to merge 🚢
